So if you’re bad at mathematics,than don’t worry fellows.These maths hacks will show you that maths doesn’t have to be complicated when u know these little tricks.
HERE ARE SOME MATHS HACKS AND TRICKS THAT WILL MAKE YOU FEEL LIKE A GENIUS
1. This super easy trick will tell you which day falls on a specific date anytime and any year
It might be a little confusing just by looking at the picture above, but you are used to it, the math is quite simple. 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!
