How can you describe the steepness of a roller coaster?1.Slope is a number which describes

the steepness of a line.

2. We use the variable m to stand for slope.

Dude, why’d

you use the letter

m?

I named it after my

Why are we learning this?

• Knowing monomial operations is Algebra standard 10.0: – Students add, subtract, multiply, and divide monomials and

polynomials. Students solve multistep problems, including word problems, by using these techniques.

• There are 2 items on the CAHSEE relating to standard 10.0

• There are 4 items on the Algebra CST relating to standard 10.0

Vocabulary Review:• Base: A number or

variable that is raised to a power.

• Power/Exponent: A number that shows how many times a base is used as a factor.

• Coefficient: A number that multiplies a variable.

• Monomial: A real number, variable or product of a real number and variables with whole number exponents.

• Examples:
