If Pinocchio's nose when he lies, what happens if he says, "My nose grows now?" If he's telling the truth, his nose won't grow. But if it doesn't grow, and he's just said it will, then he's lying.

Pinocchio's nose only grows when it doesn't grow? WHAT?

$Writing the Number 1 Using All 10 Digits #shorts There are infinite ways to write the number 1 without even using a 1. But whats the simplest way to write 1 using all 10 digits 0 to 9?

$123!’s Zeroes Trick #shorts You can determine the number of trailing zeroes on a factorial of ANY size with a pretty simple trick that involves dividing by powers of 5. First, you can do it the hard way, and multiple every number of x! (x * (x - 1) * (x - 2)...) until youre multiplying by 1 at the end, and then just count up the zeroes. Or... you can do it the smart way. Divide your original number by 5, then 5^2, then 5^3, and when youve got a fractional value, stop and add up the rounded-down whole numbers. And BAM! Thats how many trailing zeroes x! has. It really is that easy, even for a 206-digit number like 123! #shorts$
