We’re back again with a classic DYR math problem! This one might be a doozy for you. The question to the problem is as follows: 7 + 7 ÷ 7 + 7 × 7 – 7 = ?

It’s important that when approaching this math problem, you remember the order of operations, otherwise known as PEMDAS (parentheses, exponents, multiplication, division, adding, subtracting). Even with PEMDAS helping you out, these math problems can still be super tricky. So, what’s the answer? 50.

“The equation then has plus 7 divided by 7. This is interpreted as receiving a 1/7 share of $7. A 1/7 share of $7 is $1, and you’re receiving the money, so you’re going to want to add $1.”

The video continues, “We then have plus 7 times 7, that can be interpreted as receiving $7 a total of 7 different times… this means you receive $49 more. Finally, we have minus 7, which means that $7 is taken away from you… 7 + 1 is 8. 8 + 49 is 57, minus 7 is 50.”

So, from there, we substitute those results into the equation, making it 7 + 1 + 49 – 7. Now, following the order of operations, we only have addition and subtraction left to tackle, how convenient! We can evaluate this from left to right. 7 + 1 is 8, 8 + 49 is 57, and 57 – 7 is 50.
