A mathematical exercise that is viral via WhatsApp. What is it about? In the picture you can see two numbers and an outcome. They are always wrong, because, for example, in the first instance, 3 + 1 logically does not give 24. Anyway, there is a way to solve it.
THE SOLUTION:
What to do first is to subtract 3-1 and then add 3 + 1 in the first case. The result of the first count is two and the second is 4. If the two numbers are put together, the result is 24.
