<p>The properties of numbers allow us to perform various<a>arithmetic operations</a>, such as<a></a><a>addition</a>,<a>subtraction</a>,<a>multiplication</a>, and<a></a><a>division</a>. Numbers can be written both in figures and in words. For example, 2 is written as two, and 25 is written as twenty-five. For measuring height, weight, or temperature whether in sports, scores, and timings or for writing phone numbers, house addresses, and bus numbers, we use numbers to make our world easier.</p>

<p>Count real objects like fruits or toys to learn easily. Try counting in groups of 5s or 10s to spot patterns. Notice how numbers are formed, like “twenty-one” from “twenty” and “one.” For quick<a>math</a>, round numbers, for example, 49 + 77, where 50 + 77 - 1 = 126. To find how many numbers are between two values, use last - first + 1. For example, 12 - 8 + 1 = 5. </p>

<p>The number “zero (0)” plays a vital role in mathematics. It is used as a placeholder in the place-value system and serves as the additive identity in the<a>real numbers</a>. Zero represents nothing or the absence of quantity. For example, if there are three apples and now none are left, we use zero to show that.</p>

</ul><h2>History of Numbers</h2>
14
+
</ul>
25
-
<p>Numbers have not always looked the way they do today. Long ago, early humans used simple marks and<a>symbols</a>to keep count of things around them. As time passed, people created new ways to count and calculate more easily.</p>
26
-
<ul><li>Early humans used symbols and<a></a><a>tally marks</a>(////) to count things, but it was hard for large numbers.</li>
27
-
</ul><ul><li>As civilization grew, people created different symbols to represent bigger quantities.<a>Romans</a>used I, V, X, L, C, D, M but had no zero.</li>
28
-
</ul><ul><li>Around the 7th century, India perfected the<a></a><a>decimal</a>system (<a>base</a>ten). </li>
29
-
</ul><ul><li>This system used only ten digits (0-9) to show any number. Aryabhata explained the concept of zero and<a></a><a>place value</a>. For example, even Pythagoras once said, "Everything in this world is made of numbers, even music".</li>
30
-
</ul><ul><li>Arab merchants and scholars spread it to Europe, and today we call it the Hindu-Arabic numeral system, which is still used everywhere.</li>
31
-
</ul><ul><li>Scientists believe counting systems first emerged in ancient societies like Egypt, Mesopotamia, and India.</li>
32
-
</ul><ul><li>Different numeral systems were developed across the world, and as people traveled, these systems spread across continents. The Indian numeral system spread to the Middle East and Europe, becoming the base of the modern decimal system.</li>
33
-
</ul><ul><li>The Brahmi script (around 3rd century BCE, during Emperor Ashoka's time) is the earliest known numeral system of India.</li>
34
-
</ul><p>Brahmi numerals had symbols for 1-9 and special symbols for 10, 100, and 1000. They are considered the ancestors of modern numerals (0-9) used worldwide.</p>
35
-
<ul><li>Later, numbers were written in Devanagari script, which is used for Sanskrit.</li>

<h2>Types of Numbers</h2>
40
-
<p>Numbers can be classified in different ways based on how we use them and their unique features. Let's explore the different kinds of numbers.</p>
41
-
<p><strong>1. Natural Numbers - </strong>These are the basic<a>counting numbers</a>that start from 1 and go on without end. They are represented by the letter 'N'. For example: N = {1, 2, 3, 4, 5,...}</p>
42
-
<p><strong>2. Whole Numbers - </strong>Whole numbers include all<a>natural numbers</a>along with 0. They are represented by the letter 'W'. For example, W = {0, 1, 2, 3, 4, 5,...}</p>
43
-
<p><strong>3. Integers - </strong>Any positive, negative, or zero<a>whole numbers</a>are called<a>integers</a>. For example: -2, -1, 0, 1, 2,...</p>
44
-
<p><strong>4. Rational Numbers - </strong>If a number is written as p/q, it is called a<a>rational number</a>, where q is not zero and both p and q are integers. For example: 1/2, -3, 57/100.</p>
45
-
<p><strong>5. Irrational Numbers - </strong>These numbers can never be expressed as<a></a><a>fractions</a>. For example: π, √2.</p>
46
-
<p><strong>6. Real Numbers - </strong>Rational and<a>irrational numbers</a>together make real numbers. For example, 2, -5, √3, 0.5.</p>
47
-
<p><strong>7. Complex Numbers - </strong>Complex numbers consist of a real part and an imaginary part and are written in the form a + bi, where i = √(-1).</p>

<h2>Special Types of Numbers</h2>
50
-
<p>Numbers can be grouped based on their special types and usage. Let us see what are all the types of numbers.</p>
51
-
<p><strong>Cardinal numbers:</strong><a>Cardinal numbers</a>state how many of something are in a list, like 1, 5, 10, etc.</p>
52
-
<p><strong>Ordinal numbers:</strong><a>Ordinal numbers</a>define the position of something in a list, like 1st, 2nd, 3rd, 4th, and so on.</p>
53
-
<p><strong>Nominal numbers:</strong>Nominal numbers are used as names. It does not denote an actual value or the position of something.</p>
54
-
<p><strong>Pi:</strong>It is a special number approximately equal to 3.114159. Pi (π) is defined as the<a>ratio</a>of the circumference of the circle to the diameter of the circle.</p>
55
-
<p><strong>Euler’s number:</strong>Another important irrational number is approximately 2.718. It is used in advanced math, such as<a>logarithms</a>and<a>exponential growth</a>.</p>
56
-
<p><strong>Golden ratio:</strong>The<a>golden ratio</a>is a special number, approximately equal to 1.618. It is an irrational number, and its digits do not follow any pattern.</p>
57
-
<h2>Number System</h2>
58
-
<p>A<a>number system</a>is a method of representing numbers using digits, symbols, or specific rules. Each system is defined by its base and the number of unique digits it uses. A common example is the decimal system, which has a base of 10. </p>
59
-
<ul><li>Every number system uses a specific<a>set</a><a>of symbols</a>and a base that shows how many unique symbols it includes.</li>
60
-
<li>The decimal system has a base of 10 (digits 0-9).</li>
61
-
<li>The binary system has a base of 2 (digits 0 and 1).</li>
62
-
<li>In a positional system, the value of a digit depends on its position (like in the decimal system).</li>
63
-
<li>In a non-positional system, each symbol has a fixed value no matter where it appears (like in Roman numerals). </li>
64
-
</ul><p>The main purpose of a number system is to provide a clear, consistent way to write numbers for counting, measuring, and performing calculations.</p>
65
-
<h2>How to Write Numbers in Words</h2>
66
-
<p>Learn to convert numbers into words easily by breaking them into groups and writing each part with its period name, like thousands or millions.</p>
67
-
<ul><li><strong>Break the number into periods -</strong>Group the digits in sets of three using commas. For example, 37,519,248 has three periods: millions, thousands, and ones.</li>
68
-
</ul><ul><li><strong>Write each period’s number -</strong>Start from the left and write the value in each period, followed by its name, like millions or thousands.</li>
69
-
</ul><ul><li><strong>Skip the “ones” label -</strong>The last group of digits doesn’t need a period name.</li>
70
-
</ul><ul><li><strong>Use commas correctly -</strong>Place commas between the word groups just as they appear in the number. For example,37,519,248 is written as thirty-seven million, five hundred nineteen thousand, two hundred forty-eight.<p>Here is a list of numbers from 1 to 50 in words to help you write numbers in order.</p>
71
-
</li>
72
-
</ul><h2>PEMDAS</h2>
73
-
<p>The<a>term</a>PEMDAS stands for </p>
74
-
<ul><li><strong>P</strong>- Parentheses, </li>
75
-
<li><strong>E</strong>- Exponents (<a>powers</a>and roots), </li>
76
-
<li><strong>M</strong>- Multiplication, </li>
77
-
<li><strong>D</strong>- Division,</li>
78
-
<li><strong>A</strong>- Addition, </li>
79
-
<li><strong>S</strong>- Subtraction.</li>
80
-
</ul><p>PEMDAS represents the order of performing mathematical operations.</p>
81
-
<p>This can be understood better by using an example.</p>
82
-
<p> <strong>Solve :</strong></p>
83
-
<p>\(8 + \left( \frac{6}{3} \right) \times 2^{2} \)</p>
84
-
<p><strong>Step 1:</strong>Parentheses → \(6 \div 3 = 2 \)</p>
85
-
<p><strong>Step 2:</strong>Exponents → \(2^{2} = 4 \)</p>
86
-
<p><strong>Step 3:</strong>Multiplication → \(2 \times 4 = 8 \)</p>
87
-
<p><strong>Step 4:</strong>Addition → \(8 + 8 = 16 \)</p>
88
-
<p>In this example, the correct<a>order of operations</a>that are performed is shown.</p>

<h3>Problem 1</h3>
123
-
<p>Find the missing two numbers if the sum of 2 consecutive natural numbers is 37.</p>
124
-
<p>Okay, lets begin</p>
125
-
<p>Let the two consecutive natural numbers be x and x + 1.</p>
126
-
<p>\(x + (x+1) = 37\)</p>
127
-
<p>\(2x + 1 = 37\)</p>
128
-
<p>\(2x = 36\)</p>
129
-
<p>\(x = 18\)</p>
130
-
<p>\(Therefore, x + 1 = 19\) </p>
131
-
<h3>Explanation</h3>
132
-
<p>The two consecutive natural numbers are 18 and 19. The sum of 18 and 19 is 37.</p>
133
-
<p>Well explained 👍</p>
134
-
<h3>Problem 2</h3>
135
-
<p>Check whether 15 and 28 are co-prime.</p>
136
-
<p>Okay, lets begin</p>
137
-
<p>To check if 15 and 28 are co-prime </p>
138
-
<p>The prime factors of \(15 = 3 × 5\)</p>
139
-
<p>The prime factors of \(28 = 2 × 2 × 7\)</p>
140
-
<p>Since there are no common factors other than 1, 15 and 28 are co-prime. </p>
141
-
<h3>Explanation</h3>
142
-
<p>Co-prime numbers have only 1 common factor between them, that is 1. Here, 15 and 28 have only 1 in common. Therefore, they are co-prime numbers. </p>
143
-
<p>Well explained 👍</p>
144
-
<h3>Problem 3</h3>
145
-
<p>Find the quotient of 8/3 ÷ 2/3.</p>
146
-
<p>Okay, lets begin</p>
147
-
<p>To divide, \( \frac{8}{3} \div \frac{2}{3} \)</p>
148
-
<p>Multiplying\( \frac{8}{3} \) with the reciprocal of \( \frac{2}{3} \)</p>
149
-
<p>That is, \( \frac{8}{3} \times \frac{3}{2} = \frac{24}{6} \)</p>
150
-
<p>Simplifying the fraction, \( \frac{24}{6} = 4 \)</p>
151
-
<h3>Explanation</h3>
152
-
<p>To divide a fraction, we multiply the first fraction with the reciprocal of the second fraction. When we divide the given fractions, we get the quotient as 4. </p>
153
-
<p>Well explained 👍</p>
154
-

155
-
<p>Show that 5 + 7 is the same as 7 + 5.</p>
156
-
<p>Okay, lets begin</p>
157
-
<p>Add in the given order, \(5 + 7 = 12.\)</p>
158
-
<p>Swap the order, \(7 + 5 = 12.\) </p>
159
-
<h3>Explanation</h3>
160
-
<p>The commutative property of addition says the order doesn’t matter. So, \(5 + 7\) and \(7 + 5\) both give the same result: 12. </p>
161
-
<p>Well explained 👍</p>
162
-
