Who doesn’t love a good brainteaser? It’s a fun way to challenge your brain, which is probably why they’ve become so popular on the internet in recent months.
Wrap your head around this math problem: 7 + 7 ÷ 7 + 7 x 7 – 7 = ?
Can you come up with the answer? If you can’t, maybe the elementary student in your life can help.
Think you solved it? The answer is below.
It’s basic math at its finest. You might think the answer is 56, but you have to follow the order of operations, which I was taught is PEDMAS and means you need to do the following operations in this order: parenthesis, exponents, division, multiplication, addition, subtraction.
Following those rules, you must divide and multiply first, making the equation look like this:
7 + 1 + 49 – 7 = ?
Keep on going and 7 + 1 + 49 – 7 = ?
becomes 7 + 1 + 49 – 7 = 50.

The correct answer is 30.
To arrive at this solution, you’ve got to use PEMDAS, which means you’ll do the multiplication first. The equation would be:
1 + 1 + 1 + 1 + 11 + 1 + 1 + 1 + 11 + (1 x 0) + 1
= 29 + 0 + 1
