[10-(4*2)]*3

1/2w+2

Find the value of the expression.

"Evaluate the expression" means replace all the letters with their numericalvalues, and then see what number the whole expression works out to be.

You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.

To "evaluate" an expression, you need to know the value for the variables.

Unfortunately there is no expression to evaluate!

explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?

You evaluate the expression !! :)
