PEMDAS

• Pemdas means parenthesis, exponents, multiplying,
  dividing, adding, and subtracting.
• Another way to say PEMDAS is Please Excuse My
  Dear Aunt Sally.
• PEMDAS is in order from Parenthesis to
  Subtracting.

3
Parenthesis

• Parenthesis
• First, We have to look for the first step in the
  problem, which is parenthesis,
• Next, We subtract the numbers that are in the
  parenthesis.
• Example
• 9 - 5 (8 - 3) x 2 6 - 34
• 9 - 5 5 x 2 6 - 34

4
Exponents

• Exponents mean the number times the base is being
  multiplied.
• When you are doing exponents, you are multiplying
  the number by itself to the number that is the
  exponent.
• Ex 24    2 x 2 x 2 x 2    4 x 4    16

5
Multiplying

• When you multiply, you have to multiply a number
  times a number.
• When you are done doing that, you will get the
  product.
• EX 6 x 7 42

6
Dividing

• Dividing is the operation of determining how
  many times one quantity is contained in another
  the inverse of multiplication.
• Ex 4 8 2

7
Adding

• Adding is when you are putting two numbers
  together to get a number larger than those two
  numbers.
• Ex 16 85 101

8
Subtracting

• Subtracting is when you take two numbers and find
  the difference between two numbers.
• Ex 60 30 30
