Have you ever met someone who loves to answer simple questions with a fun math puzzle?
That is exactly what happened when Linda was asked a very basic question about her age.
Instead of just saying a plain number, she gave a clever mathematical expression.
She said her age is equal to 15 + (8 – 3) * 2.
At first glance, this riddle looks like a short and simple mystery.
However, solving it requires us to follow a very fundamental rule in basic math.
Let us step into this fun challenge and find out how old Linda really is.
Understanding the Rule: Order of Operations
To solve Linda’s age puzzle, we cannot just calculate the numbers from left to right.
If we work from left to right without thinking, we will definitely get the wrong answer.
In mathematics, there is an important guideline called the Order of Operations.
Many people remember this basic standard by the simple acronym known as PEMDAS.
PEMDAS stands for Parentheses, Exponents, Multiplication and Division, Addition and Subtraction.
This special order tells us exactly which part of the equation must be solved first.
By following these logical steps, we ensure that our final result is completely accurate.
Step 1: Focus on the Parentheses First
According to our math rules, the very first step is to look inside the parentheses.
In Linda’s expression, we clearly see the small equation inside the brackets: (8 – 3).
This part of the calculation is very simple and easy to do.
We simply subtract 3 from 8, which gives us a result of 5.
Now, we can rewrite the entire math expression with this new simplified value.
The original equation now transforms into 15 + 5 * 2.
We have successfully completed the first step of our logical journey.
Step 2: Do the Multiplication Before Addition
Now we are left with two operations: addition and multiplication.
Looking back at the PEMDAS rule, multiplication always comes before addition.
Therefore, we must multiply 5 by 2 before we add the number 15.
Let us multiply 5 by 2, which easily equals 10.
Our expression is now much simpler than when we first started.
It now becomes a straightforward calculation: 15 + 10.
We are just one tiny step away from discovering Linda’s true age.
Step 3: Perform the Final Addition
The last remaining step in our calculation is very simple addition.
We just need to add 15 and 10 together.
When we add 15 to 10, we get the final result of 25.
Through clear logic and order of operations, the entire puzzle is now solved.
Conclusion: Solving the Puzzle
By carefully following the Order of Operations, we solved Linda’s clever math riddle step by step.
First, we calculated (8 – 3) inside the parentheses to get 5.
Next, we multiplied 5 by 2 to get 10.
Finally, we added 15 to 10 to arrive at the number 25.
Therefore, Linda is exactly 25 years old today!
