3 <p>In mathematics, addition is one of the four basic mathematical operations. The sum is the result of adding two or more numbers. In this article, we will discuss what a sum is, how to find it, and some examples. Adding small numbers: 2 + 3 = 5 (If you have 2 apples and someone gives you 3 more, now you have 5 apples.) Adding larger numbers: 12 + 8 = 20 (If you have 12 candies and add 8 more, the total is 20.)</p>

6 <p>▶</p>

7 <p>The sum of two or more<a>numbers</a>is the result you get when you add them. A sum represents the total when items or values are combined. </p>

8 <p>To find the sum of two numbers: </p>

9 <ol><li>Line up numbers by place values </li>

10 <li>Add from right to left, carrying as needed. </li>

11 <li>Double-check with<a>estimation</a>.</li>

12 </ol><p>For example, \(2 + 2 = 4 \), where 4 is the sum and "+" is the<a>symbol</a>for<a>addition</a>. The alternative words for sum are all together, put together, how many in all, and total.</p>

13 <h2>sum of two numbers</h2>

14 <p>The sum of two numbers is the result of putting them together. Adding small numbers is easy, and you can even use your fingers to help.</p>

15 <p><strong>Example:</strong></p>

16 <p>There are three candies in a jar. You can count them by holding up three fingers.</p>

17 <p>\(3 + 3 = 6\) now there are six candies.</p>

18 <p>What if we add three more candies to the jar? Now you can count all of them again by holding up three more fingers.</p>

19 <p>\(6 + 3 = 9\) so there are nine candies in the jar.</p>

20 <p>Adding numbers is just about putting groups together and counting them all.</p>

21 <h2>How to Find Sum on Number Line</h2>

22 <p>The<a>number line</a>is the visual representation of the numbers in a straight line. To find the sum on the number line: </p>

23 <p><strong>Step 1:</strong>Draw a number line and mark numbers on it. Make sure to cover all the numbers that you want to add. </p>

24 <p><strong>Step 2:</strong>Start at zero(0). Place a point at 0, which is the starting point. </p>

25 <p><strong>Step 3:</strong>Move forward along the number line by the value of the first number. And place a point where you land. </p>

26 <p><strong>Step 4:</strong>From the landing point, move forward by the value of the next number. Repeat this for all remaining numbers. </p>

27 <p><strong>Step 5:</strong>The position of the last point on the number line is the sum of all the numbers. </p>

28 <p>For example, find the sum of 2 and 5</p>

29 <p>First, we mark the number 2 on the number line.</p>

30 <p>Then move 5 steps to the right. </p>

31 <p>We land at 7, so \(2 + 5 = 7\).</p>

35 <p>To find the sum of two numbers, add them together. Children can count on their fingers to add two numbers. For example, to add \(2 + 5\), first open 2 fingers on one hand and open 5 more fingers. There are 7 open fingers, so \(2 + 5 = 7 \).</p>
