How many legs does a spider have if it has two times more than double the number of legs a human has?
Let's think step by step below.
8
Since humans have two legs, we start by finding out what double that amount is by performing 2 * 2 = 4.

Spiders have twice that number, so we multiply 4 * 2 to find 8 legs in total.

The answer: 8
