Formula: mPn = m! / (m-n)!

I decided to calculate manually this way because of the rule of operation that must start from the inner most parentheses first and I have no choice to reverse the division by using 1/x since the problem start from the denominator portion of the fraction.
I believe that calculate this way give more accurate result.

No need to use decimals at all that way.
