📖 Let Us Begin!

Sita has 15 sweets. She gives 6 to her friend. How many sweets does she have left? We subtract to find out. Subtraction means taking away. The sign for subtraction is − (minus). The answer we get is called the difference.

Subtracting on a Number Line

A number line helps us subtract by jumping backward.

Example: 13 − 4 = ?
Start at 13. Jump 4 steps backward: 12, 11, 10, 9.
So 13 − 4 = 9.

Subtracting 1-Digit Numbers

Examples:
9 − 4 = 5    8 − 3 = 5    7 − 7 = 0

Subtracting 2-Digit Numbers (Vertical Method)

Write the bigger number on top. Subtract the ones first, then the tens.

Example: 47 − 23
Ones: 7 − 3 = 4. Tens: 4 − 2 = 2. Answer: 24.
Example: 58 − 15 = 43
Ones: 8 − 5 = 3. Tens: 5 − 1 = 4. Answer: 43.
Remember: Always write the bigger number on top when subtracting!

🎨 Activity: Take Away Game

Take 20 small stones or seeds. Take away some and count what is left. Write the subtraction sum each time. Do this 5 times with different amounts.

Example: I had 20. I took away 7. 20 − 7 = 13 left.

Sita has 15 sweets. She gives 6 to her friend. How many sweets does she have left? We subtract to find out. Subtraction means taking away. The sign for subtraction is − (minus). The answer we get is called the difference.

Subtracting on a Number Line

Start at the first number. Jump backward as many times as the second number.

Example: 13 − 4. Start at 13. Jump 4 steps back: 12, 11, 10, 9. So 13 − 4 = 9.

Subtracting 2-Digit Numbers (Vertical Method)

Write the bigger number on top. Subtract the ones first, then the tens.

Example: 47 − 23. Ones: 7 − 3 = 4. Tens: 4 − 2 = 2. Answer: 24.

Example: 58 − 15. Ones: 8 − 5 = 3. Tens: 5 − 1 = 4. Answer: 43.
