What are the goals for this investigations? What should students understand upon completion of investigation?
Order of Operations is very important because is a universal way to solve operations. It provides you an order to solve mathematical expressions involving addition, substraction, multiplication, parenthesis, division and exponents.
Key Vocabulary
- Order of Operations: Established order in which to perform mathematical operations.
1. Compute any expressions within parenthesis.
2. Compute any exponents.
3.Multiply and divide in order from left to right.
4.Add and substract in order from left to right.
How to solve a problem step by step?
(5x3) + (2x2)^2 - 6/3=30
First you solve the parenthesis " (5x3), (2x2) "
15 + 4^2 - 6/3 Then, you solve the exponents " 4^2 = 16 "
15 + 16 - 2 = 30 After that you do the division " 6/3"
And finally, you do the addition " (5x3) + (2x2)" and then the substraction "-2"
