When solving mathematical expressions, always follow the PEMDAS rule (Parentheses, Exponents, Multiplication/Division from left to right, Addition/Subtraction from left to right). In the expression 6 + 39 / 3 x (7 + 6), the correct solution is: first evaluate parentheses (7+6=13), then perform division and multiplication from left to right (39/3=13, then 13x13=169), and finally add 6+169=175. The correct answer is 175, not 195 or 7.

🔥 Almost Everyone GIVES UP! Can YOU Find The Correct Answer?Added:
What is the value of the expression 6 + 39 / 3 x (7 + 6)? Which option do you think is the correct answer to this question?
Everyone thinks this question is so easy, but it actually tricks a lot of people.
Let's dive in and break it down a step by step together. Many people when solving this question first go for the expression 6 + 39 and write this equation as 45 / 3 x (7 + 6). Inside the parenthesis.
And the next step, they go for the division between 45 and 3. And this equation simplifies to 15 x (7 + 6).
Inside the parenthesis.
And the final step, they tackle the expression inside the parenthesis and write it as 15 x 13, which ultimately gives them the answer 195.
Then, without any hesitation, they quickly say that the correct answer to this question is option D.
But, I have to say they're tricked and it's not the correct answer to this question.
Also, some other people when solving this question first go for the parenthesis and write this equation as 6 + 39 / 3 x 13.
And the next step, they go for the multiplication between 3 and 13 because they believe multiplication has priority over division.
So, this equation simplifies to 6 + 39 / 39.
Then, they go for the division between 39 and 39 because they think division has a higher priority than addition.
And they write this equation as 6 + 1, which ultimately gives them the answer 7.
And immediately, they conclude that option B is the correct answer to this question.
However, it's not the correct answer to this question.
All right. Now, let me explain it step by step how to solve this equation properly.
To solve this question, we must follow the rule that is called PEMDAS. In this rule, P stands for parentheses, E stands for exponent, M stands for multiplication, D stands for division, A stands for addition, and S stands for subtraction.
We must follow the order of operations step by step from top to bottom.
Okay, as you can see in the image, in this expression, first we have an addition sign. Then a division sign, followed by a multiplication, and finally parentheses.
We must start with the parentheses first because it has the highest priority than the other operations.
So, instead of this expression, we can write 6 + 39 / 3 * 13.
In the next step, we need to handle the division and multiplication and division have a higher priority than addition.
However, it's very important to note that in the PEMDAS rule, multiplication and division have the same level of priority.
In this case, the best thing to do is to start from the left of the expression and move toward the right, performing division and multiplication in order.
So, first we perform the division between 39 and 3. We simplify this to 6 + 13 * 13.
In the next step, it's time for the multiplication between 13 and 13 because multiplication has priority over addition.
So, instead of this expression, we can write 6 + 169, which ultimately gives us the answer 175.
Therefore, option C is the correct answer to this question.
