1. use the correct order of operation to solve the following problem: 3 × (50 – 62) ÷ 2 a. 69 b. 18 c. 21 d. 57

The correct answer is option B.  -18

Step-by-step explanation:

It is given an expression : 3 × (50 – 62) ÷ 2

To find the answer we have to use BODMAS principle

BODMAS means that the order of operations

B- Bracket, O - of , D - Division, M - Multiplication, A - Addition and  

S - Subtraction

To find the correct option

Step 1: Do the bracket first

3 × (50 – 62) ÷ 2 =  3 × (-12) ÷ 2

(Multiplication and division are in the order of appearance)

Step 2: Multiplication  

3 × (-12) ÷ 2 = -36  ÷ 2  

Step 3 : Division

-36 ÷ 2 = -18

The correct option is option B.  -18

=-18

Step-by-step explanation:

3×(50-62)÷2

Using PEMDAS,  we first evaluate the parentheses. 50-62=-12

The new expression becomes

3×⁻12÷2

We now perform the multiplication in the order in which they occur.

3×-12=-36 and -36÷2= -18

=-18
