Re: Lets see who knows this kind of math...

New function.
%. It minimizes the first number from the number's current percent in any type of brackets down to a percent that has a maximun of the second number in percent.
Example: 45(50) % 100 = 90%.
As said: Fourty five at percent fifty percented at 100 is 90 percent.

Actually, that isn't an equation.  tongue  That is an expression. An equation has to have two expressions on either side of an equals sign, expressing that they are equal to each other.

No, that's an inequality.

Re: Lets see who knows this kind of math...

So let me say this again for the people who missed it or don't understand it. 5! is a factorial expression   

5!=5X4X3X2X1

5X4=20
20X3=60
60X2=120
120X1=120

So your answer would be 120

Re: Lets see who knows this kind of math...

When I was learning factorials, we didn't have to multiply them all out, as long as we knew how to multiply them out.

What's 72 squared? Uh... 144 + 5040... 5184
518,400*7 = something
Insert calculator... 3,628,800 if I am not much mistaken.

Re: Lets see who knows this kind of math...

It means they agree with you.
Or maybe it means PF wants to change my quadratic equation. Okay, then. Graph y = x^2 + 2x +1
