How many legs does a spider have if it has two times more than double the number of legs a human has?
How many legs does a human have? ** Since humans have two legs, we start by finding out what double that amount is by performing 2*2=<<2*2=4>>4
How many legs does a spider have? ** Spiders have twice that number, so we multiply 4*2 to find 8 legs in total.
