PEMDAS is an acronym used for order of operations. P stands for parenthesis (or generally grouping), E stands for Exponent, and MDAS stands for multiplication, division, addition, and subtraction. This series is composed of three posts illustrating various examples on how to calculate using the order of operations. These posts are composed of videos that are about 10 minutes more or less. All the videos are in mixed Tagalog and English.
This post discusses how to perform basic calculations with 2 or 3 operations without parenthesis. The operations include addition, subtraction, multiplication and division.
This post discusses basic order of operations addition, subtraction, multiplication and division. The use of exponents and parentheses are also discussed. Additional explanation is provided for common misconceptions.
This post discusses more complicated calculations particularly those with nested parenthesis.
It is important that you master the order of operations because it will be used in all mathematics subjects in high school and beyond.
