If the average of 10 numbers is 10, then the sum of those numbers is 100.
\n" ); document.write( " $\"10%2A10=100\"$
\n" ); document.write( "So if you increase the 1st 5 numbers by 4 each (each means multiply), you increase that by 20
\n" ); document.write( " $\"5%2A4=20\"$
\n" ); document.write( "So add that to the previous sum, and divide by the same 10 numbers.
\n" ); document.write( " $\"%28100%2B20%29%2F10=120%2F10=12\"$ \n" ); document.write( "

\n" );
