The constant.
You evaluate the expression !! :)
A numerical expression is ' 2 + 3' A numerical equation is ' 2 + 3 = 5'.

Evaluate.
you have to deduce the variable and evaluate the expression.
to solve for the variable
Simplify !
(5n - 20) It's a binomial expression in 'n'. Its numerical value depends on the numerical value of 'n'.
You cannot find the answer to an expression!!! An expression needs to be EQUATED' to a value, for another value to be found. 2x^(2) + 5x + 12 is an EXPRESSION. Impossible to find an value for 'x'. However, 2x^(2) + 5x + 12 = 0 is an EQUATION and a result can be calculated.
Is the value obtained when all the variables have been given their value and the expression has been calculated according to mathematical rules.
