Let’s go through each problem step by step.
We’re looking at base ten blocks:
- Large squares = hundreds (100)
- Long vertical bars = tens (10)
- Small cubes = ones (1)
We need to count the blocks for each side of the minus sign, write the numbers, then subtract them — no regrouping needed!

Problem 1:
Left side:
- Hundreds: 9 large squares → 900
- Tens: 5 long bars → 50
- Ones: 5 small cubes → 5
→ Total = 900 + 50 + 5 =
955
Right side:
- Hundreds: 3 large squares → 300
- Tens: 4 long bars → 40
- Ones: 4 small cubes → 4
→ Total = 300 + 40 + 4 =
344
Subtract: 955 - 344 = ?

Problem 2:
Left side:
- Hundreds: 7 large squares → 700
- Tens: 6 long bars → 60
- Ones: 4 small cubes → 4
→ Total = 700 + 60 + 4 =
764
Right side:
- Hundreds: 2 large squares → 200
- Tens: 3 long bars → 30
- Ones: 2 small cubes → 2
→ Total = 200 + 30 + 2 =
232
Subtract: 764 - 232 = ?

Problem 3:
Left side:
- Hundreds: 6 large squares → 600
- Tens: 6 long bars → 60
- Ones: 3 small cubes → 3
→ Total = 600 + 60 + 3 =
663
Right side:
- Hundreds: 4 large squares → 400
- Tens: 2 long bars → 20
- Ones: 3 small cubes → 3
→ Total = 400 + 20 + 3 =
423
Subtract: 663 - 423 = ?

Problem 4:
Left side:
- Hundreds: 8 large squares → 800
- Tens: 3 long bars → 30
- Ones: 2 small cubes → 2
→ Total = 800 + 30 + 2 =
832
Right side:
- Hundreds: 3 large squares → 300
- Tens: 3 long bars → 30
- Ones: 1 small cube → 1
→ Total = 300 + 30 + 1 =
331
Subtract: 832 - 331 = ?
832
-331

Problem 5:
Left side:
- Hundreds: 5 large squares → 500
- Tens: 3 long bars → 30
- Ones: 6 small cubes → 6
→ Total = 500 + 30 + 6 =
536
Right side:
- Hundreds: 3 large squares → 300
- Tens: 3 long bars → 30
- Ones: 0 small cubes → 0
→ Total = 300 + 30 + 0 =
330
Subtract: 536 - 330 = ?
536
-330

Final Answer:
955 - 344 = 611
764 - 232 = 532
663 - 423 = 240
832 - 331 = 501
536 - 330 = 206
