What the last slide meant was that you need to multiple 2 by itself?

​

So you can do this: 2 x 2 ​

By Jesus Aldape Quezada

By Jesus Aldape Quezada

What that means is that you will multiply the 2 by itself 3 times like this:

​

2 x 2 x 2​

Ok, so first question. What do you do when you have this:

₂²

• you need to add

  2 + 2

• you need to do

  2 - 2

• You need to do

  2 x 2

• you need to do

  2 / 2

Multiple Choice

Ok, so first question. What do you do when you have this:

₂³

• you need to

  add 2 + 2

• you need todo

  2 - 2

• You need to do

  2 x 2 x 2

• you need to do

  2 / 2

Multiple Choice

What is the answer to that?

₂³

• 5

• 6

• 4

• 8

Multiple Choice

What is the answer to that?

₂²

• 4

• 0

• 8

• 6

Here is a new math vocabulary word for you!

​

P E M D A S .... think about how many letters you know the answer to?

​

Think about the math operations you already know!

​

You should know at least 4 letters. ​

By Jesus Aldape Quezada

What PEMDAS is that you will do 5 operations starting Left to Right.

Ok, so the P stands for Parentheses.

​

The E stands for Exponent (we just used exponents in in the first slides, remember, let me refresh your memory ₂² and ₂³​ )

​

The rest you should know! M = multiply D = / A = + and S = -​

Let me show you how we work a problem that has to do with PEMDAS.

​

5 (10 x 5) / 5

​

In this exercise we will start by doing what is inside the parenthesis first.

So, 10 x 5 = 50. Since we don't have E, we move to M. Now we do have M!

​

The number next to the ( ) parenthesis means to multiply. So, that 50 we got from 10 x 5 we're gonna multiply it by 5 ---> 50 x 5 = 250​

​

​Then, after we did M, the next step is to D. So, 250 divided by 5 = 50.
