Question

64- 18= please value blocks to find partial differences. Record your work

Answer 1

To solve 64 - 18, we use partial differences by subtracting tens and ones separately which gives us an answer of 46.

Step-by-step explanation:

To calculate 64 - 18 using value blocks and partial differences, we break down the numbers into tens and ones:

• 64 = 60 + 4
• 18 = 10 + 8

We subtract each place value separately:

1. Subtract the tens: 60 - 10 = 50
2. Subtract the ones: 4 - 8. Since we cannot subtract 8 from 4, we need to borrow 10 from the tens, making it 40 + 14.
3. Now subtract the ones again: 14 - 8 = 6
4. Add together the partial differences of the tens and ones: 40 (adjusted tens) + 6 (difference of ones) = 46

So, 64 - 18 equals 46.
