Answer:
1. (9 - 2) + (3 x 21)
= 7 + 63
=70
2. (18 + 14)/(6 + 2)
= 32/8
= 4
3. 6 + 7 x 8
= 6 + 56
= 62
4. (25 + 11) x 2
= 36 x 2
= 72
5. 3 + 6 x (5 + 4)/3
= 3 + 6 x 9/3
= 27
6. 4 x (15 - 13) + 16
= 4 x 2 + 16
= 24
7. (93 + 7) x 6 + 10
= 100 x 6 + 10
= 610
8. 12 x 3 + (100/10)
= 12 x 3 + 10
= 46
9. l(14/2) x 9l /3 x 3
= l7 x 9l /3 x 3
= 63/3 x 3
= 63
10. (16 + 8) / (4 + 2)
= 24/6
