Question

7 Solve the following expressions using BODMAS:
a [-10 - 3 {
4-(-4)} x {3 – (
5-3)}]
b 5+3 -34 – 16 - 14} = 3 [17 +(-3) x 4 - 2 x (-7)]​

Answer 1

Step-by-step explanation:

[-10-3×{4-(-4)}×{3-(5-3)}]

=[-10–3×{4-(-4)}×{3–2}]

*See below

=-10–3×8×1

=-10–24

= -34

*Next we have the {} brackets.

4-(-4) is the same as 4+4, or 8

3–2 is 1

Answer 2

Answer:

B5+3{-34-16-14}=3[17+(-3)×4-2×(-7)]
