The diameter of a human hair is 9*10^−5 meters. The diameter of a spider's silk is 3*10^−6 meters.

How much greater is the diameter of a human hair than the diameter of a spider's silk?

Would I *add, **subtract, multiply, *or *divide.*

Okay!

Here we go!

We do subtraction

9*10^(-5)-3*10^(-6)

This is 87/1000000
