\n" ); document.write( "there are 6 terms

\n" ); document.write( "1+2=3
\n" ); document.write( "5x^2-7x^2=-2x^2

\n" ); document.write( "0-3=-3
\n" ); document.write( "All terms that are alike are worked with. If a term is by itself, it must be kept, either unchanged if there is nothing to add or subtract or changed if there is. Be careful and watch for signs. Subtracting a negative makes it positive.
