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'.
Is the value obtained when all the variables have been given their value and the expression has been calculated according to mathematical rules.
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.
