Back to school: Solve this math problem without using a calculator


How much of what you learned in school do you remember today out of the top of your head? The answer for most people, I dare say, is not very much.

Of course, the basics stuck since we use them almost every day. But what about complex math? Very seldom, we encounter problems involving Pythagoras’ theorem, for example.

Should you come across a complicated equation, there is always a calculator available on your smartphone. However, for today’s math challenge, you are not allowed to use a calculator!

Solving puzzles of any kind helps to keep the brain in good shape. Besides, overcoming a challenge on your own it’s a wonderful feeling. You bring out your competitiveness and push yourself to the limit!

Good ‘ol school math

I have always devoted myself to solving brainteasers during my spare time. It can be Sudoku and Crossword Puzzles from the newspapers or optical illusions from the web.

Lately, however, I have become more interested in old math equations. It is quite fun to see if the knowledge from back then is still there!

However, it is essential to concentrate on the task in front of you. Trying to remember what the correct process is.

The correct answer is 288. How did we end up with that number? We’ll walk you through the process.

First, we have to calculate the number inside the parentheses, 9 + 3 = 12. After that, our problem looks like this: 48 ÷ 2 (12).

Then we remove the parentheses and add a multiplication sign: 48 ÷ 2 x 12.

Then we solve the problem from left to right, which results in 288.

Did you get the correct answer? If you did, Congratulations!
