This Simple Math Equation Shows You How Much You Remember From School. Can You Solve It?

Are You Smarter Than a 6th Grader—At Math?!

Most people turn their backs on math in high school either because it gets too difficult or because they don’t think they’ll use mathematics ever again after graduation. While it may be true that most people don’t need to know advanced mathematics to succeed in life, virtually all human beings need to know basic math in order to live an efficient and effective life—and to avoid being taken advantage of.

One of the keys to holding on to the math you do learn in school is to utilize it on a fairly regular basis, even if it’s only simple and brief when you do put it to use. There are plenty of solid math websites and discussion forums out there, but just trying to answer all those questions that pop-up on social media every few days could be enough practice on its own. For instance, try solving the equation below:

6 ÷ 2(1+2) = ?

Remember or record your answer!

Order of Operations: BEDMAS.

Brackets (or Parentheses)                             1st

Exponents (or Orders)                                   2nd

Division and/or

Multiplication (whichever comes first)     3rd

Addition and/or

Subtraction (whichever comes first)          4th

If you didn’t follow these steps the first time, try the equation again with the above steps in mind: 6 ÷ 2(1+2) = ?

The Answer.

1st: Brackets.

6 ÷ 2(1+2)       *1 + 2 = 3
= 6 ÷ 2(3)

2nd: Division.

6 ÷ 2(3)           *6 ÷ 2 = 3

= 3(3)

3rd: Multiplication.

3(3)                  *3 x 3 = 9

=9

So, the correct answer is 9!

Many years ago, the symbol ÷ used to be utilized to indicate that the entire product to the right of the symbol should be divided by the number to the left of the symbol. However, this technique is approximately 100 years old, and it’s now incorrect—so if you got an answer of 1 for the above equation, you’d be wrong in the year 2017 and beyond! Slate explained this back in 2013, and this journal article also outlines the transformation well.
