Question

1. Simplify: a) 118 – {121 (11x11)-(-4) – (3-7)} b) 2-[2-{2-(2-2-2)}] c) (-1){(-5)+(-25)} x (-7) – (8-10)(-4) d) 81 of [59-{7x8+(13-2 of 5)}] e) 7 – [13-2{4 of (-4)}] f) (-5) – (-48) (-16) + (-2) x 6 (Solve these questions)

Answer 1

a-
118-{121*121+4+4}
118-{14641+8}
118-14649
-14531
b-
2-[2-[2-(2-2-2)}]
2-[2-[2--(-2)]
2-[2-[2+2]]
2-[2-4]
2-[-2]
2+2=4
c-
(-1){(-5)+(-25)}*(-7)-(8-10)(-4)
(-1){(-30)}*(-7)-(8)
30*-15
=(-450)
