Will you help me understand this maths problem?
I’m taking a maths course this semester. Last week, I missed a lesson. I’m catching up, but my professor briefly described a particular problem today, and I’m having trouble with it. Here’s what she wrote:
10! / 3! x 7!
The answer, apparently, is 120.
I’ve done some research, and I know that 3! = 1×2 x 3. That’s about it, though. Help, please?
This could be called a homework question. I’m not asking for the answer, though, I’m just asking for pointers – which is fine, per the guidelines.
