Mathematics can be tricky, but understanding the order of operations is key to solving equations correctly. Whether you’re dealing with basic arithmetic or complex algebra, knowing when to do what is essential for reaching the right answer.
Breaking Down the Equation: Step by Step
Let’s take a simple-looking equation:
60 / 5(7 – 5) = ?
At first glance, it may seem easy, but the order of operations is crucial to getting the right result.
PEMDAS: Your Guide to Solving Problems
PEMDAS stands for:
- Parentheses
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
This rule tells you which operation to do first.
Step 1: Simplify Inside Parentheses
Start by solving what’s inside the parentheses.
7 – 5 = 2.
Now the equation looks like:
60 / 5(2)
Step 2: Division Before Multiplication
Next, follow PEMDAS and divide first:
60 ÷ 5 = 12
Now, the equation is:
12(2)
Step 3: Multiply
Now, multiply:
12 × 2 = 24
So, the correct answer is 24!
