Due to the fact that the exercise only involves addition and subtraction operations, we will solve it from left to right:
\( 8 - 2 + 6 = \)
PEMDAS only matters when you have different operation types! Since this problem has only addition and subtraction, you simply work from left to right. No parentheses, exponents, multiplication, or division to worry about.
This is super common with negative signs! Trace each step carefully and write down what operation you're doing. For example: 25-6 means 'take away 6', giving you 19.
No! Unlike multiplication, subtraction is not commutative. 25-6 ≠ 6-25. You must keep the exact order given and work from left to right.
Write each step clearly: , then . Don't try to do multiple steps in your head - show your work to avoid sign errors!
Double-check each step! The most common errors are: mixing up addition/subtraction signs, or trying to group operations incorrectly. Work left to right, one operation at a time.
