This is Steve, he is 11.

He lives at Fillderwood.

But Steve was hungry...

I GOT AN IDEA!

said Steve.

But before he could do anything his sister came in.

Hey Steve! Look at what I learned today!

Identity Property of Multiplicatation is any number multiplied by 1 stays the same. Ex: 3 x 1 = 3

Identity Property of Addition states that the sum of zero and any number or variable is the number or variable itself.

Ex: 4 + 0 = 4 -10 + 0 = -10 The number keeps its "identity"

Equivalent Expressions are equal to each other because they have the same value when simplified.

Numerical Expressions contains numbers and operations Ex: +,-,x,/

Algebraic Expressions contains variables. Ex: x, n, b, y.

Expressions is the mathematical phrase , numerical coefficient, variable,,constant equation. Ex: 3x + 6 = 12

Exponents number times itself and times itself again

Ex: 2 x 2 x 2 = 8

Steve called the burrito truck.

The burrito truck came in seconds.

Hot Tip: The burritos are $2.00.

I want to get 3 burritos at $2.00 ea.

Hmmm. How am I going to figure this out....

I can use Repeated Addition adding the same number (addend ) over and over.

Ex: 2 + 2 + 2 OR I can you use Multiplication 3 x 2

Did you know that Factors (3, 2) are numbers that you multiplied together to get a Product. 3 x 2 = 6

WOW

There is Commutative Property in Addition. Changing the order of addends does not change the sum. 2 + 3 = 5 3 + 2 = 5

But wait a minute....

There is Commutative Property in Multiplication. You can multiply factors in any order and you will ALWAYS get the same product. 2 x 3 = 6 3 x 2 = 6

This is crazy!!!

He bought his burritos.

and Steve is taking the bite of the burrito.

Steve's sister filming Steve

and the burrito....

and he eating the burrito.....
