For many people, algebra is plainly a stumbling hurdle. Even still, we can’t deny that arithmetic is useful in our daily lives. Its significance cannot be overstated. Even if you’ve forgotten about those wonderful school days, don’t you want to take a little trip back in time and put your wits to the test?
If so, then put your calculator away and give this equation a shot! Do you think you have what it takes?
Well, first, here is the equation:
At first glance, equations like these appear to be straightforward. However, before you begin, a word of caution: if you do not follow the correct equation order, you may not be able to complete it. This issue has been shared millions of times on the Internet and has perplexed many individuals.
So are you ready to proceed with the right order of operation?
Since we have no parentheses nor exponents, we go multiplication and division.
First, we divide 7 by 7 which gives us 1. Then, we tackle the multiplication: 7 times 7 = 49.
You’re doing great!
Our next step is to substitute these results into an equation:
Now we have 7 + 1 + 49 – 7 = ?
It means that there are only the addition and subtraction left. Let’s do it from left to right:
7+1 = 8
8+49 = 57
And finally, 57 – 7 = 50!
In fact, it isn’t the only correct way to solve this mathematical problem. If you know some other options, share them with us. Hopefully, you enjoyed this great and useful brain exercise!
