- These symbols are both used to mean division in mathematics. ÷ is used commonly in handwritten calculations and on calculators, for example, 2 ÷ 2. / is used in spreadsheets and other computer applications. See our page on Division for more. = Equals The = equals symbol is used to show that the values on either side of it are the same.

The definition of the factorial is that for any positive whole number n, the factorial: n! = n x (n -1) x (n - 2) x . . . x 2 x 1
First we will look at a few examples of the factorial with small values of n: 1. 1! = 1 2. 2! = 2 x 1 = 2 3. 3! = 3 x 2 x 1 = 6 4. 4! = 4 x 3 x 2 x 1 = 24 5. 5! = 5 x 4 x 3 x 2 x 1 = 120 6. 6! = 6 x 5 x 4 x 3 x 2 x 1 = 720 7. 7! = 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5040 8. 8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40320 9. 9! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x ...
One other value of the factorial and one for which the standard definition above does not hold is that of zero factorial. If we follow the formula, then we would not arrive at any value for 0!. There are no positive whole numbers less than 0. For several reasons, it is appropriate to define 0! = 1. The factorial for this value shows up particularly...
When dealing with calculations, it is important to think before we press the factorial key on our calculator. To calculate an expression such as 100!/98! there are a couple of different ways of going about this. One way is to use a calculator to find both 100! and 98!, then divide one by the other. Although this is a direct way to calculate, it has...
