What is a monomial?

Any number, variable, or combination of numbers and variables multiplied together.
eg. 26, x, ab, r2, 43b

What is a binomial?

Two monomials, separated by addition or subtraction

eg. x + 4, or 43b - y

How do you add two same signed integers?
What is "add 'em & keep the sign"

Write as addition: 12-(-19)
What is 12+(+19)

What is the difference between (-2)2 and -22 ?

When the negative is inside the bracket, you have to square the negative number.

Eg. (-2)(-2) = 4

When the negative is outside the bracket, you have to square the number first, then make the answer of that negative.

Eg. 2x2, and then make it negative, so -4.

12 - (6 + 2)3

12 - (8)3

= 12 - 512

= -500

Simplify the following:

12xy + 14y - 15yx + 2

-3xy + 14y + 2

12xy and -15yx can be combined because the order of the variables doesn't matter.

How do you add different signed integers?
What is "remember to subtract and keep the sign of the larger one"
500

12 - (-300) + (-24)

12 - (-300) + (-24)

= 12 + 300 - 24

= 312 - 24

= 288

500

-|3+(-12)|=

What is -9

500

[45 / (-5)] / (-8+3)2

[45 / (-5)] / (-8+3)2

= (-9)/(-5)2

= (-9) / 25

= - 0.36

If x = 6 and b = 12, find the following:

10 + 12xb - 11bx + 2b - 7b

10 + 12xb - 11bx + 2b - 7b
= 10 + bx - 5b

= 10 + (12)(6) - 5(12)

= 10 + 72 - 60

= 22
