n + 5
5 + 4 = 9
-2 + 15 + 5 The indicated sum is 18 .
This is ex. Of numerical expression 5-5, 5/5 5+5, 5*5
x + 5
The algebraic expression for "4 less than the sum of a number and 5" is (n + 5) - 4, where n represents the unknown number.

Yes. Anything which you can evaluate (calculate) to get a number is a numerical expression. Thus, all of the following are numerical expressions:5x (if the variable stands for a number)1 + 25 / 3square root of (5 / 3)In general:* Any number* Any variable that stands for a number* An addition, subtraction, multiplication, division, or power that involves numerical expressions is again a numerical expression (as long as the operation makes sense - for example, you can't divide by zero)* Many mathematical functions, with a numerical expression as a parameter - for example, sin(5 + 3), ln(10), etc.
5 (N + 1)
3(x+5)
(x + 5) + 3
The sum of n and 5 is n+ 5
4/5*(-20+5)
" 3x + 5 " does.
