Memory aid for \"order of operations\" is PEMDAS:
\n" ); document.write( "P:Parentheses first
\n" ); document.write( "E:Exponents next
\n" ); document.write( "MD: multiply/divide taken left to right
\n" ); document.write( "AS: addition/subtraction taken left to right
\n" ); document.write( ".
\n" ); document.write( "4[2(-5x+y)-y]-10(y-4x)
\n" ); document.write( "4[(-10x+2y)-y]-10(y-4x)
\n" ); document.write( "4[-10x+2y-y]-10(y-4x)
\n" ); document.write( "4[-10x+y]-10(y-4x)
\n" ); document.write( "[-40x+4y]-10(y-4x)
\n" ); document.write( "[-40x+4y]-(10y-40x)
\n" ); document.write( "[-40x+4y]-10y+40x
\n" ); document.write( "-40x+4y-10y+40x
\n" ); document.write( "group like-terms:
\n" ); document.write( "(-40x+40x)+(4y-10y)
\n" ); document.write( "(0x)+(-6y)
\n" ); document.write( "0+(-6y)
\n" ); document.write( "(-6y)
\n" ); document.write( "-6y\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
