Understanding Subtraction in Word Problems

Subtraction word problems require us to identify how much is taken away from a total. The key is to translate the words into mathematical equations.

Steps to Solve Subtraction Word Problems:

1. Read the problem carefully. Identify the total quantity and the amount being taken away.
2. Determine what is being asked. Usually, you are asked to find the remaining quantity.
3. Write the equation. Use subtraction to represent the situation.
4. Solve the equation. Perform the subtraction to find the answer.

Example Problem:

Problem: Sarah has 12 apples. She gives 5 apples to her friend. How many apples does Sarah have left?

Step 1: Identify the total and the amount taken away:

• Total apples: 12
• Apples given away: 5

Step 2: Write the equation:

$$\text{Remaining apples} = \text{Total apples} - \text{Apples given away}$$

Step 3: Substitute the numbers into the equation:

$$\text{Remaining apples} = 12 - 5$$

Step 4: Solve the equation:

$$\text{Remaining apples} = 7$$

So, Sarah has 7 apples left.
