i just accidentally stumbled on a shortcut to squaring any number with two digits (may or may not incled a decimal at any position) ending with a 5.

multiply the first digit by the number after it and then chuck a 25 on the end. place your decimal according to usual rules.

thus 2.5×2.5=6.25, 45×45=2025, 3.5×3.5=12.25, etc.

Random math tip I figured out (though I’m sure other people already knew this): if you want to know if a number is divisible by 13 without actually dividing by 13, multiply the last digit by 4 and add it to the rest of the digits, if the sum is divisible by 13, then it is.  If you keep repeating the steps you will eventually either hit 13, 26, 39 or another number that is less than 13.  If it is the former 3, it is 100% divisible by 13 (these numbers loop using the method I’m describing), but if it is the latter one, it is not and will never be divisible by 13.

With the advancing time when children are more attracted towards technology and fun-loving things, teachers need to pay attention to their students to make their studies interesting.

Decades ago, the concept of interesting education was not that in and so many like me, remained used to the boring “learning system” to learn our lessons. Many students take Mathematics as boring however, some maths teachers made the subject interesting with introducing the maths hacks. Here are some of those hacks.

Are you too lazy to do your math homework? Do you want answers that are easy to write down, but still look like answers? You've come to the right place!

This is usually my problem with math homework, and since I am a huge Dragon Ball fan, I would usually put something related to "over 9000." There are actually different ways to write "over 9000" for different types of problems. Here are the ones I came up with:

Yes/No, because it is over 9000. (in words/explain) x > 9000 (inequality) x + y = 9000 (standard form) y = -x + 9000 (slope-intercept)

If you think of any others, please go ahead and share them to the world! Any procrastinators/lazy people would be glad to hear them!
