What is 12/6 x 3-5?

If following order of operations (PEMDAS) you would multiply 6 times 3 and which is 18 and then divide by 12 but this will not give you a whole number?

3 answers

Divide first since you do it left to right
so 12/6 = 2
2 x 3 - 5
6 - 5
=1
you divide 12 by 6 first, your supposed to go in order from left to right then multiply by 3 then subtract by 5
I am taking a Algebra class right now myself and this is something that another student posted and it has helped me.. I hope it will help you.

Please----Parenthesis
Excuse---exponents
My---multiplication
Dear--division

Aunt---addition

Sally--subtraction

. Do all calculations within grouping symbols first before operations outside.
2. Evaluate all exponential expressions.
3. Do all multiplication and division in order from left to right.
4. Do all additions and subtractions in order from left to right.

Another great way to remember this is the phrase "Gee Please Excuse My Dear Aunt Sally", from high school:
Grouping, Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. One just has to remember that you do the multiplication, division, addition, and subtraction in order from left to right, it does not explain that in the phrase.

Why is it important that you follow the steps rather than solve the problem from left to right?

It is important to follow the previous steps to end with the answer that was intended for the problem. If you were to try and solve it in a different manner there is a strong possibility that you will end with the incorrect solution.
