Answer 1

a) 6+ [5+9] = 6+ 14 = 20

b) 8+ [ 4 - 6] = 8+ (-2) = 8 - 2 = 6

c) 10- [ 6+9] = 10 - 15 = -5

d) 15- [ 2 - (-4)] = 15 - [ 2+ 4] = 15 - 6= 12

e) 15 - [ 10 - 12] = 15 - (-2) = 15+ 2= 17

f) 12- [7- (-8)] = 12- [ 7+8] = 12- 16= -4

g) (-6) + [ 5+ (2-12)]= (-6) + [ 5+ (-10)] = (-6) + [ 5-10]= (-6) + (-5) = -6 -5 = -11

h) (-7) - [ 3- ( 4-9)] = (-7) - [ 3- (-5)] = (-7) - [ 3+5] = -7 +8 = 1
