Mathematics is often a nightmare not only for children, but also for adults. Some tasks require a lot of time and commitment. We spend long hours working on the notebook until we come up with a solution. There are also plenty of puzzles in the books that require you to be clever and intelligent. Remember the times and try to solve the puzzle from the textbook from 1953.
Logic math puzzle. Few people know the answer
The math puzzle appeared on the profile of user @szkolny_cwaniak on TikTok. The man found it in a 71-year-old book that his grandfather gave him. – Cross out six of the given nine digits so that the sum of the remaining numbers is equal to 20 – explained the tiktoker.
He did not provide a solution and left Internet users with this puzzle, who began to have heated discussions in the comments about the correct result. There were various proposals, people came up with many ideas. The only tip given by the author of the video in one of the comments is to listen carefully to what he is saying. So you might suspect that this is a tricky puzzle.
The puzzle divided Internet users. What is the correct result?
There are three lines of odd numbers in the puzzle: the first is three 1s, the second is three 7s, the third is three 9s. Many people said that it is impossible to get the number 20 from this combination because the result will always be odd. Nothing could be further from the truth. It was not without reason that the tiktoker advised to listen to his words. The key to solving the task is to distinguish the terms “digit” and “number”. It’s about the sum of the remaining numbers, not the digits. If you cross out the first 1, then all the 7s and the two 9s, you’ll be left with 11 and 9. When you add them together, you’ll get 20. Only now does the puzzle seem trivial, doesn’t it?
