Monday, 9/30

Ok, guys. I know the combining like terms thing is a little stressful, so let's take some time to go over how it works. 

1) Remember that, no matter what you're doing in math, you must always follow PEMDAS. 

2) Keep the distributive property in mind. Check out this graphic from scimathmn.org:

(The main thing is to remember that whatever's outside the parenthesis gets multiplied by what's inside. 

3) Remember that, with addition and subtraction, you may online combine like terms (the stuff with the same variables). 

Example:

5(3x +2) - 6x +4   ---> First step: Distribute the 5 by multiplying:

15x + 10 - 6x +4   ---> Next step: Combine like terms (they're highlighted in purple):

9x + 10 + 4

= 9x + 14

As you complete the following problems, if you have any questions, leave a comment below. Here is your assignment:

1) 6 + x - 4x + 3

2) 3(w + 3) + 4w

3) -3z + 8(z + y)

See you tomorrow!
