12 Useful Math Hacks That You Didn’t Learn In School

Mathematics, as what renowned philosopher Albert Einstein said, is poetry of logical ideas, and it’s perfectly true. Mathematics teaches us to reason out with concepts that of course include numbers.

It’s one of the subjects teach in school, yet unlike any other subjects, learning Math is quite difficult especially when there’s a lot of numbers to deal with. Maybe that’s why more people are not so fond and have ‘fear’ doing it.

Learning Mathematics way before in elementary grade is troublesome; for you to arrive with the correct solution, you need to take the mathematical sequence your Math teacher has provided you. Of course, they taught you the basic concept and traditional way of calculation, but unknown for them, there are easy and simple procedures for any math problems.

To name some of these math hacks, here are some of them:

You might be confused looking at the picture below, but the math is actually quite simple (albeit a bit elaborate). You’ll need the codes HERE, which will help you master this.

July simply has a code of 5.
20th is 6 because 7 goes into 20 twice, which is 14. 20 – 14 = 6.
2069 is 2 because the leap year code of 2068 is 1 and 2069 is 1 year after, so that’s 2.

The math can be difficult at first because there are a lot of codes, but it works out incredibly well once you pick it up. Here’s a separate example:

January 3, 2014 is a Friday, right?

So, January, according to the table, is 6, and we handle days by using multiples of 7. We don’t need to, so it’s actually just 3 in this case. Next we need to know the closest leap year, which was 2012. That has a year code of 1 and 2013 is 2 years after, so 3 again.

We get 6 + 3 + 3 = 12 – 7 = 5! FRIDAY!
