III. Evaluate the following expressions using GEMDAS or PEMDAS rule.
16. 21 - 27 + 3 =
17. 23 + 5 X 4 =
18.(3 + 7)x 5 =
19.27 - (6 + 5) + 9 =
20.24 + 6 x 2 =
21. (2 x 52) + 3 =
22. 35 - 6 x 3 =
23. (7-3)' x 52 =
24. 48 + 12 + 8 =
25. 12-3+ 18 + 6 x 3 =
16. 21 - 27 + 3 =
17. 23 + 5 X 4 =
18.(3 + 7)x 5 =
19.27 - (6 + 5) + 9 =
20.24 + 6 x 2 =
21. (2 x 52) + 3 =
22. 35 - 6 x 3 =
23. (7-3)' x 52 =
