-3a^2+4b+c; a=-3,b=-2,c=-1

Step One: -3( )^2+4( )+( )

Note that I'm recommending this BEFORE the numbers go in!

Do you share my belief in the critical role of ( ) in evaluating algebraic expressions?

OR

Are you thinking this is too much detail and most students don't need to do this?

And I haven't even gotten to replacing -7-3 by (-7)+(-3)!
