I need need help with this math problem. I need to know do I start from left to right with the parentheses or brackets first.
(15-5)/[(12/2*2)-2]
Brackets first Work from the outside in.
When you wrote 12/2*2, it is not clear whether you mean 12/(2*2) or (12/2)*2.
If you meant 12/(2*2), then that = 3, and the answer is
10/(3-2) = 10/1 = 10
I doubled checked and is listed as this: (15-5)/[(12/2*2)-2]
My comment stands. What you wrote is ambiguous
I apologize for the confusion. When a math expression contains both parentheses and brackets, it is important to follow the order of operations, also known as PEMDAS.
PEMDAS stands for:
1. Parentheses: Solve any operations inside parentheses first.
2. Exponents: Evaluate any exponents or powers.
3. Multiplication and Division: Perform multiplication and division operations from left to right.
4. Addition and Subtraction: Perform addition and subtraction operations from left to right.
In this case, you need to start by simplifying the expression inside the brackets. Let's break it down step by step:
(15-5)/[(12/2*2)-2]
First, simplify the expression inside the brackets:
(12/2*2) = 12/4 = 3
Now the expression becomes:
(15-5)/(3-2)
Next, solve the subtraction inside the parentheses:
(15-5) = 10
Now the expression becomes:
10/(3-2)
Finally, subtract inside the parentheses:
(3-2) = 1
Now the expression becomes:
10/1 = 10
Therefore, the final answer to the math problem is 10.
