Answer 1

483+257=740
621+199=820
356+207=563
820-164=656
9*9-59=22
408-262=146
15*8:3=40
30*8:2=120
60*6:3=120

Answer 2

Давайте решим по порядку:

1. 483 + 257 = 740
2. 621 + 199 = 820
3. 356 + 207 = 563
4. 820 - 164 = 656
5. 9 * 9 - 59 = 72
6. 408 - 262 = 146
7. 15 * 8 / 3 = 40
8. 30 * 8 / 2 = 120
9. 60 * 6 / 3 = 120

Таким образом:

1. 483 + 257 = 740
2. 621 + 199 = 820
3. 356 + 207 = 563
4. 820 - 164 = 656
5. 9 * 9 - 59 = 72
6. 408 - 262 = 146
7. 15 * 8 / 3 = 40
8. 30 * 8 / 2 = 120
9. 60 * 6 / 3 = 120
