explain how you could show five less than a number using an expression

n - 5

You replace the n with any number you want.

n-5=35. So the n is 40. 40-5=35.

To show five less than a number using an expression, you can use the subtraction operator. Let's call the number "x".

The expression for five less than a number "x" would be:

x - 5

Here, the "-" symbol represents subtraction, and we subtract 5 from the number "x" to get five less than the original number.
