We know that money is integral for every exchange. If you buy a chocolate, a toy, or candies, you have to pay cash for them. Learning about money in mathematics helps students make wise choices in daily life, like comparing prices, calculating savings, and learning more about business, shopping, banking, and finance. In this article, we will learn more about money, types of money, its importance, and how it can be appropriately managed.

What is Money in Math?

Money is the basic medium of exchange. For any activities and services, basic charges are deducted from daily lives. For example, to buy commodities like dresses and food, to visit a zoo or museum, and to consult a doctor, we have to pay money. Money is measured and valued in different units, such as dollars, euros, and rupees. The smaller denominations are measured in units such as cents or paise—for example, 1 dollar and 10 cents.

Money in mathematics includes calculating change, interest, budgeting, understanding taxes, and discounts. Mathematics related to money is essential in fields such as finance, banking, and commerce.

History of Money

The concept of money has existed since ancient civilizations. Way before money was introduced, people used the barter system for transactions. These transactions involved exchanging goods and inventory for other goods and services. As the barter system became less effective, people started to exchange shells, salt, and precious metals. The minting of the first metal coins dates back to around 600 BC in Lydia, present-day Turkey. Later, during the Tang dynasty in China, paper money was introduced. In the 17th century, banks in Europe started issuing notes, which led to the development of modern banking systems.


In recent times, after the development of the internet, online banking, including digital transactions, was introduced. Now we use various forms of money, such as digital transactions, credit cards, cryptocurrency, notes, and coins.

Properties of Money

Money has various properties, and learning about them can help us understand how money works. Some properties of money are mentioned below:
 

  • Durability: Money, in the form of paper, must be able to withstand wear and tear overtime. In many countries, paper money is still considered good enough, even if there is minor wear and tear.
  • Portability: One of the properties of money is that it can be easily carried around and transferred from one person to another. 
  • Uniformity: Uniformity brings standardized transactions into the picture. Minting money of different denominations allows easy flow of transactions.
  • Limited Supply: If the money has to maintain its value, the money that is being minted must not be produced in excess. If produced in excess, it decreases the value of the currency, thus leading to inflation. 
  • Acceptability: If money has to be called money, it has to be accepted everywhere as a medium to exchange goods and services. 
     


If students learn these properties, they will understand the concept of money and how to use them.

Types of Money

Money can be classified into various categories. Learning them will help students understand the differences and use them efficiently. Types of money are mentioned below:

  • Currency: Currency refers to the physical form of money in circulation within an economy. It includes banknotes and coins issued by the government or central bank and used as a medium of exchange for everyday transactions. Currency is a part of fiat money, but the term specifically refers to the tangible money people use daily. For example, US Dollars (USD), Euros (EUR) and Indian Rupees (INR) are all currencies.
  • Commodity Money: Commodity money is the money that has an intrinsic value to it. Commodity money includes commodities like gold, silver, or other valuable materials. 
  • Fiat Money: Fiat money means the money that is government issued. This type of money does not have any intrinsic value but is accepted as a legal tender. For example, paper money and coins. 
  • Digital money: After the introduction of the internet, money no longer needed to be only physical in nature. Direct transfer of money from one bank account to another made electronic transactions possible. This paved the way for online transactions and digital wallets. 
  • Representative Money: This type of money is backed by a commodity, like gold or silver, but it is not made by using the commodity. For example, gold-backed certificates. 
  • Cryptocurrency: Money that is decentralized and digital is called cryptocurrency. Cryptocurrency is secured by cryptography. Some types of cryptocurrency are Bitcoin and Ethereum.
  • Fiduciary Money: This refers to a type of money which is accepted based on trust. The transaction is done between two trusted parties, the payer and the payee. The money is accepted as a medium of exchange and is not recognized as legal tender by the law. 
  • Commercial Bank Money: This type of money is the money that is created by banks through lending and borrowing and deposits. It exists in the form of digital balances.

How to Count Money

Counting money is an essential and everyday skill. Let us see how we can count coins and notes together. 

Step 1: Identify the value written on each coin and note. The color, style, and size of each denomination will always be different. 

Step 2: Group similar coins and notes together. For example, group all the $1 notes in a pile, $5 notes in another pile, and so on. This makes counting easier and faster.

Step 3: Now count each group separately. Count the total value of each group instead of counting everything at once. For example, if you have five $10 notes, count them as \(5 × 10 = $50\). 

Step 4: Once each group has been counted, add the totals to get the final amount. For example, if you have $50 in notes, $15 in coins, and a single $10 note. Then, the total is \($50 + $15 + $10 = $75\). 

Step 5: Always confirm the counted money by double-checking. You can count again in the same method or count backwards, from the highest notes to the lowest coins.

Importance of Money for Students

Tips and Tricks to Master Money

If students want to master the concept of money, they can follow the following tips and tricks to understand the concept better:


Budgeting and Money Management: Students can start tracking their income and expenses to understand where the money is going. Money can be managed by following the 50/30/20 rule. The rule is to reserve 50% of our total income for our needs, 30% for our wants, and 20% for savings and investments. Students must learn to plan their expenses like vacations, gifts, and medical emergencies. 

Smart Saving: Students can follow the 'pay yourself first' rule, which means save before spending. They must learn to save at least 10% - 20% of their income, no matter how small. 

Avoid Unnecessary Debt: Students must be cautious about keeping debts. Students must always understand that there is going to be an interest rate whenever they borrow money from instant loan apps, and it will bring them more debt if they do not pay their EMIs on time.

Smart Spending: Students must be wise when it comes to spending their money. They must use student discounts on food, transportation, and subscriptions. Instead of spending outside on food, students can practice eating home cooked meals as it saves money. 

Financial Literacy: As long as the students have financial literacy, they will be able to understand the concept of money easily. Students can read books related to financial literacy like 'Rich Dad Poor Dad' and 'The Psychology of Money' to understand more about money and savings. They can also follow podcasts, YouTube channels, and finance blogs.

Make money learning hands-on: Parents and teachers can use real or play money for counting, sorting, and role-play shopping to help children understand value through authentic experiences.

Teach the value of choice: Explain that money involves decisions and trade-offs, helping children think before they spend and choose wisely. Teach them to compare prices and understand market values to make wise decisions. 

Encourage goal-based saving: Guide children to set small saving goals. Please encourage them to use jars or piggy banks to track progress, building discipline and patience.

Give money management lessons: Show students good financial behavior, such as budgeting and comparing prices, because children learn directly from adult examples. And allow children to manage small allowances or classroom funds, which helps them practice budgeting and accountability. 

Promote gratitude and sharing: Encourage children to appreciate what they have and donate a portion of their money or items to develop generosity and awareness.

Problem 1

A businessman invests 60% of his money in stocks and 40% in bonds. If his total investment is $10,000, with stocks yielding 8% profit per year, and bonds yielding 5% profit per year, what is his total profit?

Okay, lets begin

The total profit is $680.

Explanation

Step 1: Calculate the amount invested in each:
 

Stocks: 60% of $10000 = $10000 × 0.60 = $6000

Bonds: 40% of $10000 = $10000 × 0.40 = $4000

Step 2: Compute the profit from each investment:
 

Profit from stocks: $6000 × 8% = $6000 × 0.08 = $480

Profit from bonds: $4000 × 5% = $4000 × 0.05 = $200

Step 3: Total Profit = $480 + $200 = $680.

Problem 2

A retailer marks up an item by 25% over its cost price and then offers a 20% discount on the marked price. If the cost price is $80, what is the final selling price and the retailer’s profit or loss?

Okay, lets begin

The final selling price is $80 and there is no profit or loss.
 

Explanation

Step 1: Calculate the Marked Price:
 

Cost Price = $80

Markup Percentage = 25%

Markup amount = 25/100 × 80 = 20

Marked price = 80 + 20 = 100

Step 2: The retailer offers a 20% discount on the marked price

Discount amount = 20/100 × 100 = 20

Final selling price = 100 - 20 = 80

Step 3: Calculate the profit and loss:

Profit or Loss = selling price - cost price

SP = $80

CP = $80

Profit or Loss = 80 - 80 = 0.

Problem 3

A person decides to save $200 per month. Every six months, they receive a bonus equal to 50% of a month’s savings. How much money will they save in one year?

Okay, lets begin

The person will save $2600 in one year.
 

Explanation

Step 1: Understanding the Savings Plan

The person saves $200 per month regularly.

Every six months, they receive a bonus equal to 50% of a month’s savings (which is 50% of $200 = $100).
 

We need to calculate the total savings for one year (12 months)
            

Step 2: Calculate the Regular Savings

Since the person saves $200 every month, the regular savings for 12 months will be:

200 × 12 = 2400.

Step 3: Calculate the Bonuses

The person gets a bonus every six months.

Since a year has 12 months, they will receive 2 bonuses

Each bonus is $100, so the total bonus amount for the year is:

100 × 2 = 200.

Step 4: Total savings calculation

Now, we add the regular savings and bonuses:

2400 + 200 = 2600.

Problem 4

Sarah earns $1500 per month. She spends 30% on rent, 20% on food, 10% on transport, and saves the rest. How much money does she save?

Okay, lets begin

She saves $600 per month.
 

Explanation

Step 1: Calculate the rent
 

Rent = 30/100 × 1500 = $450

Step 2: Calculate the food expense
 

Food = 20/100 × 1500 = $300

Step 3: Calculate transport expense
 

Transport = 10/100 × 1500 = $150

Step 4: Calculate the total expenses
 

$450 + $300 + $150 = $900

Step 5: Savings = Income − Expenses
 

$1500 - $900 = $600

Problem 5

Riya went to a stationary shop and bought the following items: 1 notebook for Rs. 25.50, 2 pencils for Rs. 5.75 each and 1 eraser for Rs. 4.25. If Riya gave the shopkeeper Rs. 50, how much money will she get back?

Okay, lets begin

₹8.75.

Explanation

Step 1: Find the total cost of each item: 

1 Notebook - 1 × 25.50 = 25.50

2 pencils - 2 × 5.75 = 11.50

1 eraser - 1 × 4.25 = 4.25

Step 2: Add the cost of all items: 

₹25.50 + ₹11.50 + ₹4.25 = ₹41.25

Step 3: To find the change, subtract the total cost from the amount paid: 

₹50.00 − ₹41.25 = ₹8.75
