IQ test in a minute: a math example that will confuse anyone

Many people are confident in their math skills, but statistics say the opposite: according to studies, more than 60% of adults have difficulty solving even simple arithmetic problems if different mathematical operations are intertwined. Want to test yourself? Try an example that mixes roots, degrees, addition and multiplication.

A math riddle to test your attention:

√81 + (3² × 2) – 5(4 + 1) = ?

Such tasks train the brain better than regular memory exercises. Psychologists say that regularly solving math examples improves concentration, reduces the risk of dementia, and strengthens short-term memory.

Interesting facts for math lovers:

• According to a study by Oxford University, people who regularly solve math problems are 25% less likely to suffer from memory problems in old age.
• Just 15 minutes a day spent on simple tasks helps the brain stay active and significantly improves cognitive ability.
• Scientists have proven that math improves not only logical but also creative thinking, because it trains the brain to find unconventional solutions.

What is the right way to solve such problems?

Do not rush to write the answer at once – solve sequentially, observing the order of operations:

1. Extract the root:√81 =9.
2. Let’s take it to a power:3² =9.
3. Multiply:9 × 2 =18.
4. Calculate the sum in parentheses:4 + 1 =5.
5. Multiply the resulting sum by 5:5 × 5 =25.
6. Add and subtract in order:9 + 18 =27♪ then 27 to 25 ♪2.

Answer:2

If you arrived at this answer, great! Your math ability is above average. If you are wrong, don’t feel bad: regular practice, which we will help you with :), will make you an expert.

Keep training your brain by solving problems regularly, and you will notice how not only your logical thinking will improve, but also your ability to make quick decisions in a variety of life situations.
