What is the general formula for the factorial notation?

Hmmmm. Hard?

n!= 1*2*3*4*...*n-1*n

I have been missing from school and we have just learned it. So I am not very good at it.

There is quite a lot on Wikipedia

/wiki/Factorial

Which includes the general formula and a worked example for 5!

If you have missed a lot of school, you may need extra help to get caught up. You should speak to your teacher about extra tutoring. In addition, there are many websites that can be helpful:

http://mathforum.org/
including Ask Dr. Math

etc.

Work hard to get caught up. It's no fun always being on that "treadmill."
