is the answer to the following =1 or 9? 6/2(1+2)

Question

Simply trying to understand the application of the orders of operations.

Answer 1

The correct order of operations is as follows: parenthesis, exponents, multiplication/division (as it appears from left to right), addition/subtraction (as it appears from left to right).

 

First solve the equation in the parenthesis.

6/2(1+2)

6/2(3)

 

Then go left to right and solve for all of the multiplication and division in order.

6/2(3)

3(3)

 

ANSWER: 9

Answer 2

If we use order of operation (PEMDAS), we will have

 

6 / 2(1+2)

 

Working with parenthesis first will give us

 

6/2(3)

 

 

Multiply or divide from left to right. 

 

3 * 3 = 9
