Revision of Numbers

5

Step 1: Riya has 2 pencils and Mohan has 3 pencils. Step 2: Altogether means we add them: 2 + 3. Step 3: 2 + 3 = 5. Step 4: Together they have 5 pencils. Always add when the question says altogether!

7

Step 1: We need to add 0 and 7. Step 2: Zero means nothing. When you add nothing to a number, the number stays the same. Step 3: 0 + 7 = 7. Step 4: The answer is 7. Adding zero to any number gives the same number!

1

Step 1: We have the numbers 3, 7, 1, 5. Step 2: Let us arrange them in order: 1, 3, 5, 7. Step 3: The number that comes first when counting is the smallest. Step 4: 1 comes first, so 1 is the smallest number. The smallest number has the least value!

3

Step 1: We start with 4 flowers. Step 2: We give 1 flower away, so we subtract: 4 - 1. Step 3: 4 - 1 = 3. Step 4: 3 flowers are left. When something is given away, we subtract!
