2). 1/2 * 4* 3 = 6

3). 10 * 3 * 10 = 300

4). 2(5) + 2(7) = 10 + 14 = 24

5). 4 * 2² = 4*4 = 16

6). 7 * 8 * 2 = 56 * 2 = 112

7). 1.3 * 15 = 19.5

8). 3(6 + 11) = 3* 17 = 51

9). 45/9 = 5

10). 2 *14² = 2* 196 = 392

11). 5 * 12 * 7 = 60 * 7 = 420

12). 1/2 * 9 * 12 = 54

13).1/2(24)(9 + 21) = 12 * 30 = 360

14). 14 * 13 = 182

15). 16 * 8 * 5 = 640

16). 75/5 = 15

17). 2(5²) = 2 * 25 = 50

18). 8(2.5 + 4.2) = 8 * 6.7 = 53.6

19). 1/2(3)(5 + 6) = 33/2 = 16.5

20). 3.14(6²) = 3.14 * 36 = 113.04
