Order of Operations
Evaluate the following arithmetic expression: 3 + 4 x 2 It seems that each student interpreted the problem differently, resulting in two different answers.
- Let's look at some examples that involve more than two operations.
- Perform all additions and subtractions, working from left to right.
- For example:
(4 + 5) + 6 = 5 + (4 + 6)
(x + y) + z = x + (y + z)
Numbers that are multiplied can be grouped in any order.
- The rectangle area is 3(4 + 6) = 3(10), or 30.
