Question 628135: I have some equations in the following format (finding the nth term of an algebraic expression)
( n ) a^(n-(r-1)) * b^(r-1)
r-1
I don't understand what the (n & r-1) terms in the parenthesis at the beginning of the expression are. From the solution, it suggests that the first term ends up resolving to a division of factorials such as:
(6! / ((6-3)! * 3!)) where n=6 and r=4...
I just dont understand how they got from the first form to the factorial form.

Question 629293: Solve this equation 28÷7+2×3=?
28 / 7 + 2 * 3 is the equation
by the order or arithmetic, you scan left to right and do multiplies and divides in the order you encounter them.
your equation becomes:
(28/7) + (2*3) = x
i let x = the result until we can figure out what the result is.
simplify this equation to get:
4 + 6 = x which results in:
x = 10
the result of that calcultion is equal to 10
