Subtraction Using Expanded Form
To subtract numbers using the expanded form, we follow the given steps.

• Write each number in the expanded form.
• Subtract the values at each place.

• Find the sum of the subtracted values.

Example 6: Subtract 32 from 56 using the expanded form.
Solution: Step 1: Write each number in the expanded form.

56 = 50 + 6
32 = 30 + 2

Step 2: Subtract the values at each place.
T O Tens Ones

5 6 5 0 6

– 3 2 – 3 0 – 2
2 0 4

Step 3: Add the numbers to find the sum of the subtracted values.
T O
2 0

+ 4

2 4 So, 56 – 32 = 24.
