I have more examples of adding like terms on the lesson page on the GED Math Crash Course. sites.google.com/view/gedmathcrashcourse/algebra/combining-like-terms
5y-7y= -2y. Quick question, because there is a y after the five, and a y after the seven, would it not make the answer -2y^2? Aka Negative two y squared?
Got this on my vid list, Brandon, because it is a very common struggle, but THE VARIABLE PORTION OF A TERM (letters and exponents on the letters) NEVER CHANGE when adding and subtracting. We are literally just counting up how many y's we have or how many y's we owe. No matter how many y's we have, they are still just y's. Like if you had 5 apples but owed me 7 apples, you'd end up still owing me 2 apples. The apples would still be apples, not some new complicated type of fruit after you handed them over. When MULTIPLYING, we see y's accumulate. For example 5y(-7y) would give -35y^2. That is because exponents are used to express REPEATED MULTIPLICATION and in that problem we see y multiplied in TWICE, two y's MULTIPLYING is y^2. Does that make sense?
Hi Kate, You say that rows are the what one uses to add downwards, but I have always thought that these were called columns and rows were left to right. Can you please clarify this point? Thanks, Hope
