EXAMPLE: 785 - 244 =

700 - 200 = 500

80 - 40 = 40

5 -4 = 1

500 + 40 + 1 = 541

1. 368 - 335 = 33                                           

300-300=0

60-30=30

8-5=3

2. 435 - 224 =211

400-200=200

30-20=10

5-4=1

3. 675 - 343 =332

600-300=300

70-40=30

5-3=2

4. 463 - 321 = 142

400-300=100

60-20=40

30-10=20

5. 749 - 445 =304

700-400=300

40-40=0

9-5=4

6. 443 - 341 =102

400-300=100
