Question

Can someone write out the steps so I understand?
14 + 18 ÷ 2 x 18 - 7

Answer 1

`\Huge \boxed{169}`

Explanation:

To solve this problem, first you have to use the order of operations stands for parenthesis, exponents, multiply, divide, add, & subtract the numbers from left to right.

Please Excuse My Dear Aunt Sally!

PEMDAS

P- Parenthesis

E-Exponent

M-Multiply

D-Divide

A-Add

S-Subtract

First, multiply & divide numbers from left to right.

`\displaystyle 18/2=9`

`\displaystyle 9*18=162`

Add & subtract numbers from left to right.

`\displaystyle 14+162-7`

`\displaystyle 162+14=176`

`\displaystyle 176-7=\boxed{169}`

So, the correct answer is 169.

Answer 2

To solve use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

REMEMBER: IF A STEP IS NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .

14 + 18 ÷ 2 x 18 - 7

Now comes the problematic part, in which many people get confused. Although in the PEMDAS order it shows multiplication before division, you must remember that multiplication and division are "paired." This means that you will apply these two operations in the order they come first in the expression as you read it from left to right. In this case that would be division first then multiplication.

NOTE: This rule also applies when you are dealing with addition and subtraction in the same expression

Division

14 + 18 ÷ 2 x 18 - 7

18 ÷ 2 = 9

14 + 9 × 18 - 7

Multiplication

14 + 9 × 18 - 7

9 × 18 = 162

14 + 162 - 7

Addition

14 + 162 - 7

14 + 162 = 176

Subtraction

176 - 7

= 169
