# Calculation of CN

Calculate:

$\left(\genfrac{}{}{0px}{}{789}{786}\right)-\left(\genfrac{}{}{0px}{}{789}{3}\right)$

Correct result:

x =  0

#### Solution:

$\left(\genfrac{}{}{0px}{}{789}{786}\right)-\left(\genfrac{}{}{0px}{}{789}{3}\right)=\frac{789!}{786!3!}-\frac{789!}{3!786!}=0$ We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you! Tips to related online calculators
