Many people get it wrong: Are you clever enough to pass this math test?

Classic brain training methods are perhaps puzzles like crosswords or sudoku, but in recent times I have become more and more attracted to the type of challenge you’ll see below.

This types of puzzles have been flooding the web lately, probably because they are really fun!

These are old classic mathematical problems. When you were in middle or high school.

These tests are more fun when you find yourself trying to remember the math you learned as a child.

Can you figure out the correct solution?

Knowledge degrades

So now I’m going to treat you to a math problem designed for school students. But it’s not that simple for those of us who graduated decades ago. It’s easy to forget the order of operations as we grow older.

Now to the brainteaser – can you figure out the answer? Try to think back on the mathematical rules!







To help you along, we’ve provided 3 solutions.

We can already reveal that “C: Something else” can be discarded.

So either 24 or 154 is correct. But which one?

2 × 5 + 3 + 1 × 11

If you remember, multiplication is always done before addition. Therefore:

10 + 3 + 11

There we go!

The solution is 24.


Very few Americans get this right without a calculator: Can you solve it?

Can you solve this equation – without a calculator?

Okay, now to the challenge.

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

What do you think the right answer is?

Hmm, now how did this work again?

Think long and hard and you might be able to remember!

The answer is written underneath this image.






Here’s the answer

The right answer is 104.

But how come?

First of all, before we do anything else, we need to solve the multiplication, and 25 * 0 gets us 0.

So what remains is 50 + 50 – 0 + 2 + 2 which gets us 104.

So the answer is 104.

Did you get the right answer? If so, then congratulations!
