<p><strong>Addition:</strong>We need to calculate the<a></a><a>sum</a>of different things we buy, how much we spend on shopping, how much we save, and so on. The addition method is used to combine amounts of various things. For example, Sam buys a water bottle for $20, a bag for $30, and a pen for $2. </p>

<p>\($20 + $30 + $2 = $52\).</p>
4
<p>\($20 + $30 + $2 = $52\).</p>
5
<p>So, the total cost is \($52\).</p>
5
<p>So, the total cost is \($52\).</p>

<p><strong>Subtraction:</strong>The subtraction method helps us to determine how much money is left with us after spending the money. It also tells us how much money we need to buy something. This method enables us to find the difference between amounts. For instance, Junaid has $35 and spends $25 on a shirt. How much does he have left?</p>

<p>\($35 - $25 = $10\).</p>
9
<p>So, Junaid has $10 remaining.</p>

<p>So, Junaid has $10 remaining.</p>

<p><strong>Multiplication:</strong>To calculate the amount for<a>multiple</a>items or repeated payments, we use the multiplication method. For example, a cup of coffee costs $5.76, and you want to buy 3 cups. This method is useful to calculate the total cost of coffee: </p>

<p>\( $5.76 × 3 = 17.28\)</p>
12
<p>So, the total cost for three cups of coffee is \($17.28\). </p>
12
<p>So, the total cost for three cups of coffee is \($17.28\). </p>
13
<p><strong>Division:</strong>If we need to distribute money equally, such as dividing a bill among friends or allocating equal funds, we use the division method. For instance, Mia and her 3 friends go out for lunch. It costs a total of $60. How much should each person pay equally?</p>
