It’s been a long time since you went to school – and for every year that goes by, the time where you used to sit down at your desk, doing assignments and math problems, drifts further and further away.
Going to school was difficult growing up, but oh how important it was. You learned to read, write, and plenty of other useful skills.
With math, however, it’s a bit different. The advanced formulas, techniques, and order of operation are harder to remember if you don’t use them often.
Of course, we use basic math for everything, but how much do you actually remember from those slightly longer, complex calculations you had no problem solving when you were younger?
The older you get, the more important it is to take care of yourself. Regular exercise and a good diet are always a must, but the fact is that it’s also important to keep your brain healthy.
A good way to keep the mind sharp is by solving some brainteasers. Perhaps the most common are crosswords or sudoku – but neither is better nor worse than the other.
Can you solve the equation?
Something else that puts everything inside the head to work is a challenging math equation. On the web, you can find plenty of problems to solve – with different difficulties.
You can test yourself and find out how much you actually remember while healthily exercising your mind, a win-win situation!
Here comes today’s challenge!
The picture below shows a problem taken out of a school book, however, everyone online is tearing their hair out trying to find the solution. There’s only one rule – you can’t use calculators.
Here’s the problem! What do you think is the answer?
Don’t stress, look closely and try to figure out how to get the right solution.
Below the next picture, we’ll show you the answer.
The correct answer is 104.
Always start with the multiplication
How did we end up with that solution?
First, you calculate the multiplication 25 x 0, which of course becomes 0. This is one of the basic rules of mathematics.
Then we have: 50 + 50 – 0 + 2 + 2, which results in 104.
So the important detail, to get to the right answer, is to start with the multiplication. Otherwise, things get messy.
Did you solve it on your own? Good job then!
