Northfield had 24 basketballs and 15 soccer balls. someone donated 8 basketballs, 3 soccer balls, and 4 tennis rackets. Ezekiel took half of the equipment home for his own use. Sam brought 1 basketball, 1 soccer ball, and a pair of tennis rackets from home. Hope said that soccer wasn't a good game, and popped all but 2 of the soccer balls. In response, Jack brought 4 soccer balls from home. Phillip took 14 of the basketballs and launched them in a giant catapult into space. Michael took 2/3 of the soccer balls and cooked them like chicharones and ate them. How much sports equipment do we have now?

I can add and subtract polynomials both horizontally and vertically.

basically, we are combining like terms. Let's review what like terms means in this context:

1. The terms (monomials) must have the same variable (or variables)

2. The terms must have the same exponent (or exponents) on those variables

3. If both #1 and #2 are true, you can combine those terms

There are two methods for doing this:

Horizontal Method and Vertical Method

What about subtraction?

Distribute the negative (subtraction) sign into the second polynomial, then add

When you distribute the negative, the sign of each term in the second polynomial will change

If you want to do the first couple of problems together, watch up here. Otherwise, you can start your work on your own.
