Greatest Common Factor
Greatest Common Factor - largest number that divides a set of numbers
Least Common Multiple - smallest shared product of a set of numbers
Helpful Hints:
- you must list all factors to find the largest one
- multiples are like counting by the number (ex. multiples of 3 are 3, 6, 9, 12, etc.)

Topic 5: Solving One- and Two-Step Equations
Topic 6: Solving Multi-Step Equations
Definitions:
Like Terms - must have same variable(letter) and same exponent(small number, up high)
Helpful Hints:
Combine like terms that are on the right side of the equal sign
Move all letters to one side of the equal sign using opposite signs (generally, left side)
Move all numbers to the other side of the equal sign using opposite (generally, right side)
You should have something like 2x = 4 at this point, divide by the number that is with the letter to get the number by itself(if it looks more like x/2 = 4 then set up a proportion by putting a 1 under the 4....like this: x/2 = 4/1 and solve like a proportion.
