You can put this solution on YOUR website!
to solve this type of problem go backwards through the statement and do the opposite of what it says!
\n" ); document.write( "So we start with six and instead of dividing by 9 we multiply by 9. This gives
\n" ); document.write( "6 X 9 = 54
\n" ); document.write( "next we subtract 33 instead of adding 33
\n" ); document.write( "54 - 33 = 21
\n" ); document.write( "Next we double instead of halving
\n" ); document.write( "21 X 2 = 42
\n" ); document.write( "Finally we add 12 instead of taking 12
\n" ); document.write( "42 + 12 = 54
\n" ); document.write( "The number you started with was 54!
\n" ); document.write( "(Just to check, try running through the statement using 54 as the number first thought of and see if you end up with 6.
\n" ); document.write( "Here goes...
\n" ); document.write( "54 - 12 = 42
\n" ); document.write( " $\"42%2F2\"$ = 21
\n" ); document.write( "21 + 33 = 54
\n" ); document.write( " $\"54%2F9\"$ = 6
\n" ); document.write( "yay! the check works so our answer is correct) \n" ); document.write( "

\n" );
