Solution without a calculator. Children are doing well. Doroles have a problem

There are many types of puzzles, puzzles and rebuses on the web. Those are very popular for perceptiveness, i.e. consisting in indicating differences or searching for a non -matching element. True emotions, however, arouse logical tasks and mathematical equations, under which Internet users often have fierce discussions. Will they show the correct answer this time? Be careful because you’ll find a solution a little lower!

A simple mathematical puzzle. For children it is a pick

This time your task will be mathematical equations. Although at first glance it does not look complicated, many people forget about a certain principle, so the resulting result is often incorrect. Interestingly, adults have a problem mainly, because it concerns knowledge from primary school, which is easy to forget. Meanwhile, children solve them quickly. What is the equation? How much it is 8: 2 (3+2) =?

What is the order of performing? Adults often forget

In the above equation, it is important The order of performing actions that will allow us to know the correct result. How should it run?

• First, actions in brackets (after them power, but here we do not have them).
• Then multiplying and dividing (from left to right).
• Finally, adding and subtraction (from left to right).

Solution of the equation. How much did it take?

This means that in 8: 2 (3+2) we should first add 3 and 2 to each other, which will give us 5, so the equation will look as follows: 8: 2×5. Going further, we have division and multiplication, the order of which is as if on an equal footing, so it should be done from left to right. So we must first divide 8 by 2, which will give us 4. At the end it is enough to multiply 4 and 5. So the final result was 20. Have you been able to guess? Did you like mathematics at school? We invite you to participate in the poll and commenting.
