P = 160/16
Let P be the final points, A be the awarded points, F be the number of times the skater falls. So we have P = A - 1.2*F
Subtract 25 from whatever variable you use for "a number". If your number is "x", then the expression becomes "x - 25".
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
10^-1 = 0.1
The expression is 9*x.

A numerical expression is an expression that uses number. For example, if a teacher told you to write four plus six subract two , you would simply write it in number form. 4+6-2.
You cannot write an algebraic expression for that, you need an equation. The equation is n - 6 = 4
How do you write an expression
X = " a number " X + 20
( n - 16 )
