These types of challenges are getting more and more common online. And they’re not impossible to solve by any means – we just need some good old-fashioned arithmetic that we were taught all those years ago.

I think that’s one of the reasons these types of tricky problems are so popular – we can satisfy our competitive spirit as well as feel some nostalgia for our school days.

Can you solve this math equation – without a calculator?

Okay, now to the challenge.

Below is a tricky equation. Can you solve it without using a calculator?

Tricky!
