You probably think you’re smarter than a middle schooler. If you want to know for sure, try your hand at this basic math problem. It’s harder than it looks — even if you think you have a solid grasp of good old PEMDAS.
Now, go to the riddle today:

9 + 9 + 9 – 9 + 9×0 – 9×3 + 9 = ?
( 9 + 9 + 9 – 9×3) + 9 – 9 + 9 x 0 = 0 + 0 + 0 = 0

Answer:
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.
