10*9*8*7*6*5*4*3*2*1 = 10!

Im totally confused with this.

How can multiplying all of those numbers together only equal 10???

I think she means 10! or "ten factorial".

And yes, the math statement is true by definition.

Leo is correct.

! following a number is the mathematical "factorial" symbol, NOT an exclamation point.

It appears often in probability equations.

4! = 1*2*3*4 = 24, for example.
