What does the little number (exponent) mean?

It is the number of times that you multiply.

Today’s New Vocab (1 of 4)What is a variable?

What is an expression?

It is an unknown number. For example, we usually use x or y.

A mathematics problem without an = sign.

If it doesn’t have an = , don’t write = .

Today’s New Vocab (2 of 4)Expand and Evaluate 46

The base is the number that gets multiplied. The exponent is number of times the base gets multiplied.

Today’s New Vocab (3 of 4)Expand and simplify 𝑥5(𝑥3)(x)

What do you do with the exponents? When you are multiplying variables, you ADD the exponents.

Expand (x)(x)(x)(x)(x)(x)(x)(x)(x)

When in doubt, expand it out !!! 𝑥5+3+1 𝑥9or

Today’s New Vocab (4 of 4)Simplify the following expressions.

Does 2(3x + 4) = 6x + 8 for all numbers?

Pick any number at random and substitute it in for both x’s.

If x = 5, is it true? Yes, it is true for all numbers.

2(3(5)+ 4) = 6(5) + 8

2(15+ 4) = 30 + 8

38 = 38

2(19) = 38
