Evaluate the expression. 7! • 4! - 6! a) 120,240 b) 120,020 c) 120,000 d) 119,420

When a number is followed by an exclamation point (!) it means that number gets multiplied by all the numbers below it.

So 7! = 7*6*5*4*3*2*1 = 5040

4! = 4*3*2*1 = 24

6! = 6*5*4*3*2*1 = 720

Now the equation is:

5040 * 24 -720

5040 *24 = 120960

120960 - 720 = 120240

The answer is A.
