Your task is to solve this equation in 10 seconds or less. Think you’ve got it? Before you start throwing out answers, let’s review the basics: the order of operations. Remember, following the proper order is key to getting the right result.
The Order of Operations
In mathematics, we follow a specific sequence to solve equations. This is known as PEMDAS, which stands for:
- Parentheses
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
When solving any equation, operations inside parentheses come first, followed by exponents. Next, we handle multiplication and division from left to right, and finally, we do addition and subtraction, also from left to right.
Now, let’s apply this to the equation step by step:
Step 1: Multiplication and Division
First, handle the multiplication and division, starting from left to right:
7 × 7 = 49
Next, divide:
7 ÷ 7 = 1
Now, the equation looks like this:
49 – 1 + 7
Step 2: Addition and Subtraction
Continue by performing the subtraction and addition, also from left to right:
49 – 1 = 48
Then, add:
48 + 7 = 55
So, the final answer is 55.
Why This Equation is Trickier Than It Seems
What makes this equation tricky is that many people rush through it and either ignore or forget the proper order of operations. Without applying PEMDAS, it’s easy to come up with the wrong answer. Some might mistakenly solve it from left to right without considering multiplication and division first, which would lead to incorrect results.
