What is the difference between simplifying an algebretic expression and evaluating an expression when we aren't supposed to solve the expression.
\n" ); document.write( "------
\n" ); document.write( "We can \"solve\" equations. That solving process may involve simplifying.
\n" ); document.write( "-----
\n" ); document.write( "We can only \"simplify\" algebraic expressions. We cannot \"solve\" them.
\n" ); document.write( "------------------------------\r
\n" ); document.write( "\n" ); document.write( " Problem is
\n" ); document.write( "4-5(2-1)+(3-4)^2
\n" ); document.write( "----
\n" ); document.write( "This is an algebraic expression. It is not an equation.
\n" ); document.write( "--------------
\n" ); document.write( "= 4-5(1)+(-1)^2
\n" ); document.write( "------
\n" ); document.write( "= 4-5+1
\n" ); document.write( "----
\n" ); document.write( "= 0
