Math can be tricky. Some equations seem trivial at first glance. In practice, this is not entirely the case. When we start solving them, it turns out that they require more time and attention. How did our ancestors deal with mathematical operations? Try to solve the problem of intelligence, which 95% of Poles fail. According to , it comes from 1950.
Quick intelligence test. Solve a math problem
When solving equations, the correct order of operations is crucial. First we perform operations in brackets, then multiplication or division, and finally addition and subtraction. It is worth remembering this when performing calculations, because one error may affect the entire result. The best example is a task that appeared on an IQ test 74 years ago. Few people knew how to solve them. How will you cope? Here it is:
8+8:8+8*8-8=?
IQ test from 1950. What calculations need to be made?
People who took the test gave as many as four answers: 64, 65, 72, 80. Only 5% of Poles gave the correct result. To solve the puzzle correctly, you need to remember the order in which you perform the actions. The first thing we should do is divide and multiply: 8:8=1, 8*8=64. Now do the calculations from left to right: 8+1+64-8=65. So the correct answer is 65. If you came up with something different, you most likely forgot about the good order of operations. Try again, keeping these rules in mind, and you will surely succeed. Show this task to your loved ones and see how they cope. It’s also a good way to learn together with .
