technology and computing programming languages# Where is the exclamation point on my calculator?

If you haven't done so already, press [2nd][MODE] to get to the Home screen. Follow these steps to type a factorial in your

**calculator**: Enter the number you would like to take the factorial of. and press [4] to choose the factorial symbol (it looks like an**exclamation point**.)

Beside this, what does the exclamation mark mean on a calculator?

Factorials are very simple things. They're just products, indicated by an **exclamation mark**. For instance, "four factorial" is written as "4!" and **means** 1×2×3×4 = 24. ("enn factorial") **means** the product of all the whole numbers from 1 to n; that is, n! = 1×2×3×

**mathematics**, the symbol represents the factorial operation. The expression n ! means "the product of the integers from 1 to n ". For example, 4! (read four factorial) is 4 × 3 × 2 × 1 = 24.

Beside above, where is the exclamation point on a TI 84 Plus?

To enter the factorial symbol (!), press [math], press the right arrow key 3 times to get to the “PROB” tab, scroll down to the fourth option (the factorial symbol) and press enter. Now, just press enter to evaluate the factorial!
