Question 1186044

What is the value of 12C2?
<pre>NEVER, EVER follow that woman's suggestion regarding answering most math problems!
This is NOT done the way she shows!
{{{highlight_green(matrix(1,11, " "[12]C[2], "=", (12 * 11 * 10!)/((12 - 2)! * 2!), "=", (12 * 11 * 10!)/(10! * 2!), "=", (6cross(12) * 11 * cross(10!))/(cross(10!) * cross(2!)), "=", 6(11), "=", 66))}}}
This problem DOESN"T require a calculator as some people - including the other person - would suggest!
