When I calculated y-2y on the Web 2.0 CALC it came out to be -y..... How do you get that answer?? Help?
y-2y does equal -y
What is your problem with that???
How do I get that answer ?
y-2y In front of the y is an invisable 1 or even +1 It is really 1*y
=1y-2y 1y and -2y are like terms so you can add or subtract them together.
Does that help?
