According to the rules of the order of arithmetic operations, we must first solve the multiplication exercises.
We place them inside of parentheses in order to avoid confusion during the solution:
We then solve the multiplication exercises:
Lastly we solve the rest of the exercise from left to right:
0
\( 100+5-100+5 \)
Mathematics has a specific order of operations (PEMDAS) that everyone follows. If we solved left to right, the same expression could have different answers depending on who solves it!
Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). Remember: Please Excuse My Dear Aunt Sally!
Adding parentheses around multiplication like is helpful for clarity but not required. It helps you see which operations to do first!
That's normal! In this problem, we get . Just continue with the remaining operations: .
Zero is a valid answer! It means all the positive and negative terms perfectly cancel out. Always double-check by substituting back into the original expression.
