Mathematics Chapter Two Lesson Four Order Of Operations Mathematics Matrix Grant Alyssa
Directions Step 1: You have to type a number sentence in a row, for example: 285+93÷(3−2)x3x4²
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.
Parentheses Then you have to rewrite the number sentence until you get to the parentheses. Then solve what is in the parentheses. 285+93÷1x3x4² The 1 is the answer in the parentheses. You have to subtract 3-2. Which is 1.
Exponents Then you have to check if there is any exponents. If there is then you have to solve. 285+93÷1x3x16 The 16 is the answer for the exponents. You have to do 4x4. Which is 16.
Division Then you have to check if there is division or multiplication. Which ever one comes first in the number sentence. 285+93x3x16 93 is the answer for division. You have to do 93÷1. Which is 93.
Multiplication Then you have to do multiplication. 285+279x16. 279 is the answer for the multiplication. Then you have to multiply 93x3. Which is 279.
Multiplication Continued Then you have to do multiplication again because there is still multiplication in the number sentence. 285+4464 4464 is the answer for the other multiplication. Then you have to multiply 279x16. Which is 4464.
Addition Now you have to solve what is left. 285+4464=
Answer Now you write the answer: 4749 is the answer for the problem.
