A student says that a + b = a because the variable b cancels. How do you respond?
\n" ); document.write( " c + b c
\n" ); document.write( "----------------------------------------------
\n" ); document.write( "[(a+b])/(c+b) = (a/c)
\n" ); document.write( "----
\n" ); document.write( "I say the student is wrong because you cannot cancel terms, only factors
\n" ); document.write( "that are common to numerator and denominator.
\n" ); document.write( "==================
