Math Hypno 😴

Math is so confusing it can hypnotize you and eat you. This is :l me.

I am not affiliated with any of the external websites, although I check them from time to time and find them helpful.

Understand their terms of use and use them wisely.

Let's start with divisibility rules:

Numbers divisible by 2:

One's digit ends in: 0,2,4,6,8

Numbers divisible by 3:

All digits added for that number are also divisible by 3.

Ex.: 123 = 1+2+3 = 6

Since 6 is divisible by 3, so is 123

Numbers divisible by 4:

The last 2 digits are divisible by 4:

Numbers divisible by 5:

One's digit is either 0 or 5

Prime Number "Formulas":

Prime formula works for n is equal to positive integers 1 up to 79:

f(n) = n2-79n+1601

Prime formula works for n equal to positive integers 1 up to 40:

f(n) = n2-n+41
