 Amsco Integrated Algebra I: Order of Operations
This is a free lesson from our course in Amsco's Integrated Algebra
 
   
This lesson explains basic concepts of the order of operations, taking forward the leanings earlier about binary operations, factors of a number, prime number, base, and exponent. When a numerical expression involves two or more different operations, we need to agree on the order in which they are performed. The expressions with grouping symbols-say parentheses ( ), are simplified always performing the operations within parentheses first and then follow the correct order of operations (MDAS).(More text below video...)

(Continued from above) The procedure is:
• Simplify any numerical expressions within parentheses or within other grouping symbols, starting with the innermost.
• Simplify any powers.
• Do all multiplications and divisions in order from left to right.
• Do all additions and subtractions in order from left to right.
For example: if you evaluate 3 + 6 x (5 + 4) ÷ 3 - 7 using the order of operations, the recommended steps are:
3 + 6 x (5 + 4) ÷ 3 – 7 = 3 + 6 x 9 ÷ 3 - 7 Parentheses
3+ 6 x 9 ÷ 3 - 7 = 3 + 54 ÷ 3 - 7 Multiplication
3 + 54 ÷ 3 - 7 = 3 + 18 - 7 Division
3 + 18 - 7 = 21 - 7 Addition
21 - 7 = 14 Subtraction
The video above will explain in detail with the help of several examples.
 
   

As many of you know, Winpossible's online courses use a unique teaching method where an instructor explains the concepts in any given area to you in his/her own voice and handwriting, just like you see your teacher explain things to you on a blackboard in your classroom. This particular lesson includes the teacher's instruction, practice questions as well as end-of-lesson quizzes for practice. As we mentioned above, you can enroll in our online course in Trigonometry by clicking here.

The format of Winpossible's online courses is also very suitable for teachers who are using an interactive whiteboard such as Smartboard on Promethean in their classrooms, because the course lessons can be easily displayed on such interactive whiteboards. Volume pricing is available for schools interested in our online courses. For more information, please contact us at educators@winpossible.com.
