Answers Key

1

313 = 6 + 307

-307 = 6 - 313

2

2 = 820 - 818

818 = 820 - 2

3

478 = 47 + 431

-431 = 47 - 478

4

576 = 719 - 143

143 = 719 - 576

5

631 = 468 + 163

-163 = 468 - 631

6

151 = 872 - 721

721 = 872 - 151

7

307 = 640 - 333

333 = 640 - 307

8

221 = 203 + 18

-18 = 203 - 221

9

549 = 677 - 128

128 = 677 - 549

10

407 = 824 - 417

417 = 824 - 407
