1.
1. Evaluate:
(a) (-36) + (12 + 0)
(b) (25 + 5) - (5 + 5)
(c) 26 = {(-14) + 1}
(d) {(-20) + 5} = {(-5) + 2}
(e) {(-25) - (-7)} = {(-2) + (-1)}
(1) {1024 = (-32)} + {(-125) = 5)
2. Simplify:
(a) (-5) - [1 – {9 - 6 + 2 (7 x 2)}]
(b) 49 = (–7) * (-2) – (12 – 3) + (3 of 4)-7
(C) 121 + (-11) 3 + 8 {(-4) + 7(6 - 8 + 7)} (d) (-96) = (-6) - 6+ (8 of 7) - 3 - 1
(e) 12 - [24 + 10 - {(-10) + 4(8 – 2 * 3+6)}] (1) 2 - [6 - 7 +(-3) - {2 x 4 – (21 = 3
(g) {(-186 +52) - (-40)} + 2 + (-35)
(h) {3 of (–70)} = 10 + {14 x 8 (5 – 8 + 4);
(i) 50 - [18 - 26 + (46 + 9 x 2 – 10)}] - (-3) (j) 12 – {3 % (45+ (-9))} 4] - (-32) -7
