Hi, my son and I are stuck on his homework. He has done all the sheet except 4 similar questions. Please can I give you an example.....Q. Think of a number, add on 3,multiply it by 2, subtract 2, divide by 2, subtract your first number. What is your answer?

\n" ); document.write( "Think of a number,
\n" ); document.write( "

\r\n" );
document.write( "I am thinking of the number N\r\n" );
document.write( "

\n" ); document.write( "add on 3,
\n" ); document.write( "

\r\n" );
document.write( "I get N+3\r\n" );
document.write( "

\n" ); document.write( "multiply it by 2,
\n" ); document.write( "

\r\n" );
document.write( "I get 2(N+3), which upon distributing is 2N+6.\r\n" );
document.write( "

\n" ); document.write( "subtract 2,
\n" ); document.write( "

\r\n" );
document.write( "I get 2N+6 - 2 which after combining terms gives 2N+4\r\n" );
document.write( "

\n" ); document.write( "divide by 2,
\n" ); document.write( "

\r\n" );
document.write( "I get  which equals , and upon canceling,\r\n" );
document.write( "    , becomes N+2 \r\n" );
document.write( "

\n" ); document.write( "subtract your first number.
\n" ); document.write( "

\r\n" );
document.write( "My first number was N, so subtracting it gives N+2-N, which\r\n" );
document.write( "after simplifying, gives 2\r\n" );
document.write( "

\n" ); document.write( "What is your answer?
\n" ); document.write( "

\r\n" );
document.write( "My answer is always 2 no matter what N is.\r\n" );
