Directions

• Step 1 You have to type a number sentence in a
  row, for example
• 28593(3-2)x3x4²

3
PEMDAS

• Then you have to write PEMDAS on top of the
  number sentence. That means
• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction
• An easy way to remember the steps is by this
  saying
• Please Excuse My Dear Aunt Sally.

4
Parentheses

• Then you have to rewrite the number sentence
  until you get to the parentheses. Then solve what
  is in the parentheses. 285931x3x4²
• The 1 is the answer in the parentheses.
• You have to subtract 3-2. Which is 1.

5
Exponents

• Then you have to check if there is any
  exponents. If there is then you have to solve.
• 285931x3x16
• The 16 is the answer for the exponents.
• You have to do 4x4. Which is 16.

6
Division

• Then you have to check if there is division or
  multiplication. Which ever one comes first in the
  number sentence.
• 28593x3x16
• 93 is the answer for division.
• You have to do 931. Which is 93.

7
Multiplication

• Then you have to do multiplication.
• 285279x16.
• 279 is the answer for the multiplication.
• Then you have to multiply 93x3. Which is 279.

8
Multiplication Continued

• Then you have to do multiplication again because
  there is still multiplication in the number
  sentence.
• 2854464
• 4464 is the answer for the other multiplication.
• Then you have to multiply 279x16. Which is 4464.

9
Addition

• Now you have to solve what is left.
• 2854464

10
Answer

• Now you write the answer
• 4749 is the answer for the problem.
