Drag the simplified value into the box to match each expression.

Answer 1

Answer:

The answers are as follows: 12 106 42

Step-by-step explanation:

Given: $18 - 4^2 + 5 \times 2$  

Using BODMAS rule (Bracket, Of, Division, Multiplication, Addition and Subtraction) we would calculate $18 - 4^2$ separately and $5 \times 2$ separately and add them. So we have $18 - 16 + 10 = 2 + 10 =12$.

Now for the second question: $9^2 + 4 \times 7 - 3$. we would get $81 + 28 - 3 = 106$

Next, $5^2 - 4 + 7 \times 3$. This could be written as:  $25 - 4 + 21 = 42$. Hence the answers.
