The Associative Law say that it doesn't matter how we group the numbers, so:
\n" ); document.write( "(a+3+5)= (a+3)+5= a+3+y, etc., any way you group them you get the same answer.
\n" ); document.write( "------------------------------------------
\n" ); document.write( "By the way, it also applies to multiplication:
\n" ); document.write( "(a×b)×c = a×(b×c)
\n" ); document.write( "--------------------------------------------
\n" ); document.write( "How is it used? Sometimes it is easier to add or multiply in a different order. But you can't mix them. The law applies to pure multiplication or pure addition:
\n" ); document.write( "3+2+5= 11 any way you add them
\n" ); document.write( "3*2*5= 30 any way you multiply them.
\n" ); document.write( "BUT:
\n" ); document.write( "(3*2)+5 is not the same as 3+(2*5)
\n" ); document.write( "J \n" ); document.write( "

\n" );
