Answer:
The answers are as follows: 12 106 42
Step-by-step explanation:
Given: [tex]$ 18 - 4^2 + 5 \times 2 $[/tex]
Using BODMAS rule (Bracket, Of, Division, Multiplication, Addition and Subtraction) we would calculate [tex]$ 18 - 4^2 $[/tex] separately and [tex]$ 5 \times 2 $[/tex] separately and add them. So we have [tex]$ 18 - 16 + 10 = 2 + 10 =12 $[/tex].
Now for the second question: [tex]$ 9^2 + 4 \times 7 - 3 $[/tex]. we would get [tex]$ 81 + 28 - 3 = 106 $[/tex]
Next, [tex]$ 5^2 - 4 + 7 \times 3 $[/tex]. This could be written as: [tex]$ 25 - 4 + 21 = 42 $[/tex]. Hence the answers.
