  • Graphical form: \"0.78x%2B1\" simplifies to \"3.2074\"
  • Text form: 0.78x+1 simplifies to 3.2074
  • Cartoon (animation) form: \"simplify_cartoon%28+0.78x%2B1+%29\"
    For tutors: simplify_cartoon( 0.78x+1 )

DETAILED EXPLANATION

\n" ); document.write( "
Look at \"0.78%2Ahighlight_red%28+x+%29%2B1\".
Replaced x with 2.83
It becomes \"0.78%2Ahighlight_green%28+2.83+%29%2B1\".
\n" ); document.write( "
Look at \"highlight_red%28+0.78%2A2.83+%29%2Bhighlight_red%28+1+%29\".
Replace constants in expression: \"highlight_red%28+0.78%2A2.83+%29\",\"highlight_red%28+1+%29\" with \"highlight_green%28+3.2074+%29\"
It becomes \"highlight_green%28+3.2074+%29\".
Result: \"3.2074\"
