I ran into a math problem the other day. It was one of those going around as a “brain teaser” with the problem being followed by “the majority of people will get this wrong”. Of course no where on the page was the correct answer. Multiple people in the comments guessed as to the correct answer and some provided explanations as to how their answer was right.

Here is the problem: 7+7/7+7*7-7

Written out: 7 plus 7 divided by 7 plus 7 multiplied by 7 minus 7

Here is a hint: The Math Order of Operations is PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction). Keep in mind that when it comes to Multiplication and Division and Addition and Subtraction each carries the same precedence. So it isn’t that you have to solve a problem strictly in the order of Multiplication then Division and/or Addition and then Subtraction. In some cases doing so leads to the wrong answer.

The correct answer is below the line down at the bottom of this post.

The correct answer is 50.

Well, getting this correct makes up for the other mistakes I made today. I always get embarrassed when I flub a math Jeopardy question.

Can blame it on the distracting music they play. 🙂
