Lesson 4: Order of operations introduction

# Order of operations introduction

The order of operations is a crucial math concept that ensures consistent results when solving problems with multiple operations. By following PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction), students can accurately evaluate expressions and avoid common mistakes. Mastering this skill is essential for success in mathematics. Created by Sal Khan.

## Want to join the conversation?

• When Sal said "armed by the order of operations" my brother yelled "oh no, its another D-Day, and I died laughing at that
• D-DAY is war, like the world war 1, 2 , or 3
• Wouldn't it be addition before subtraction to make the last answer 17?
• If you want to do addition first, you would have 20-2+1, but -2+1=-1, so 20-1=19.

first, 5 x 2 = 10.
Then, 10 + 3 = 13
• Good job! 👍
• I dont get it can someone explain?
• I learned Pemdas in like, 5th grade
• I learned it in fourth what state/county are you in, only so I know what district taught fifth
• my teacher calls it pemdas
