Let's work backwards.
\n" ); document.write( "Find the ones that are.
\n" ); document.write( " $\"+1%5E2=1\"$
\n" ); document.write( " $\"2%5E2=4\"$
\n" ); document.write( " $\"3%5E2=9\"$
\n" ); document.write( " $\"4%5E2=16\"$
\n" ); document.write( " $\"5%5E2=25\"$
\n" ); document.write( " $\"6%5E2=36\"$
\n" ); document.write( " $\"7%5E2=49\"$
\n" ); document.write( " $\"8%5E2=64\"$
\n" ); document.write( " $\"9%5E2=81\"$
\n" ); document.write( " $\"10%5E2=100\"$
\n" ); document.write( "That makes $\"10\"$ .
\n" ); document.write( "From $\"1\"$ to $\"100\"$ , there are $\"100\"$ numbers.
\n" ); document.write( "So $\"100-10=90\"$ of them are not squares of an integer.
\n" ); document.write( " \n" ); document.write( "

\n" );
