\n" ); document.write( "---
\n" ); document.write( "80*80 means 80 multiplied by 80
\n" ); document.write( "we use asterisk (*) to show multiplication, rather than using \"x\", because \"x\" is often used for variables such as:
\n" ); document.write( "x + y = 180
\n" ); document.write( "---
\n" ); document.write( "h = sqrt( xx + yy )
\n" ); document.write( "80 = sqrt( 2xx )
\n" ); document.write( "80*80 = 2xx
\n" ); document.write( "xx = 40*80
\n" ); document.write( "x = 56.568542
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "each car traveled about 57 miles
