Step 1: Write in multiplication form:

Step 2: Multiply Out

Recall that ! means factorial in math. This means we multiply the number by all positive integers less than itself. In other words, this...

Becomes

This is a great job for a calculator, which yields:

Step 1: Evaluate
Factorial-Multiply the number in front of the exclamation point by every number below until I hit

Step 1: Evaluate the parentheses first

Step 2: Multiply the outside by the final value in Step 1..

Step 1: Find

Step 2: Find

Step 3: Subtract the values from step 1 and step 2:

The answer is

Step 1: Recall definition of factorial...

Factorial is a mathematical expression where you multiply by every number below it until I hit . To find each number, subtract from the previous number

Step 2: Write out

Step 1: Define Factorial

Factorial is a mathematical expression which you multiply the number in front of the exclamation point by every number below it until you hit 1..

Step 2: Evaluate
