Work through these problems, making sure to solve the part in the parentheses first. Notice that # 9 includes brackets, and #10 includes brackets and braces.
 1. 5 - (3 + 1) = 5 - 4 = 1 2. 20 - (28 - 9) = 20 - 19 = 1 3. (43 - 2) + 6 = 41 + 6 = 47 4. (18 + 23) - 3 = 41 - 3 = 38 5. 48 - (25 + 7) = 48 - 32 = 16 6. 87- (32 + 21) = 87 - 53 = 34 7. (35 + 14) - 9 = 49 - 9 = 40 8. 28 + (46 - 31) = 28 + 15 = 43 9. ([20 - 2 + (46 - 15) + 2] - (9 + 4) = [18 + 31 + 2] - 13 = 51 - 13 = 38 10. {[18 - 2 + (14 – 3) - 3] + (27 – 3) + 2} + (7 – 5) = {[16 + 11 - 3] + 24 + 2} + 2 = {24 + 26} + 2 = 50 + 2 = 52
