How Does This Math Problem Work?
5 Answers
I am in a math class and I'm interested in how this works.
In brackets ( ) put a 12 at the top and a 4 under it with no line "this is not dividing", and that should equal 495. Why?
My teacher is horrible, I need to with draw from this class.
Thanks everyone

One of the most annoying parts perhaps of mathematics is the obscure and sometimes overlapping notation. Numbers in brackets arranged in a column means a vector to me, and when I do the 12!/8!*4! thing I would write 12C4 which means the same and avoids a clash. But notation is extremely tricky and even in the highest levels of mathematics there is often inconsistency over what things mean.
