MULTIPLYING MONOMIALS. Quick and Easy Steps
1.
2.
3.
multiply the coefficients
keep all the variables and/or numerical bases
add the exponents of the like variables/bases
Ex 1:
x7 x3
Ex 2:
= x10
b/c x7 = xxxxxxx
x3 = xxx
when we multiply them
x is a facto
Adding Polynomials => finding the sum of, combining, 2 or more
polynomials.
Example 1:
(3x + 4y 2) + (5x + 2y + 8)
Way 1: line up by place value
We can think of a polynomials place
value as like terms. All terms with
x have the same place value, all terms
Classifying Polynomials =>
(and DEGREE)
MONOmial =>
certain polynomials have special names, understanding
PREFIXES will help in the naming of these polynomials
since mono means one
a monomial is a one term expression formed from a number, a variable or th

Dynamite Divisibility
How do we know if one number is divisible (divides evenly into) another number?
Easy
A number is divisible by 2 if
The number is even that is, it ends in 0, 2, 4, 6, or 8
A number is divisible by 3 if
The face value (sum of its digit
