Question

Now simplify the following:
(i) 9 + {6 + 5 x 3 – (9÷3 – 8 x 2)} (iv) 9 – [4 + {3 – (5 – 8 – 6) – (-3 + 2)}]
(ii) 2- [6 – {2+5 x (6-3)}] (v) 8 + [6 – 3 – {5 + (2 - 8 ÷ 2)}]
(iii) -8 – [7 – {2 + 5 – (6 – 7 – 3)}] (vi) 7 – [-3 + 5 of 6 – {-5 + (6 x 3 -8)}]

Answer 1

Answer:

(i) 9+{6+5×3-(3-16)}

=9+(6+5×3-(-13))

=9+(6+5×3+13)

=9+(6+15+13)

=9+34

=43
