Look closely at the image above.
It looks like a simple math test written on paper.
At first glance, it seems very easy to solve.
However, many people get the wrong answer because they forget basic math rules.
Let’s take a look at the equation together.
The problem is: 450 ÷ 50 × 5 + 40.
We also have three choices to choose from: A) 85, B) 75, and C) 65.
Which option do you think is correct?
To find the right answer, we must follow the order of operations in mathematics.
This rule is often called PEMDAS or BODMAS.
According to this rule, we do operations inside parentheses first, then exponents.
Next, we handle multiplication and division from left to right.
Finally, we do addition and subtraction from left to right.
In our problem, we have division, multiplication, and addition.
Since division and multiplication have the same priority, we must calculate them from left to right.
First, let’s solve the division part: 450 ÷ 50.
450 divided by 50 equals 9.
Now, our equation becomes: 9 × 5 + 40.
Next, we perform the multiplication part: 9 × 5.
9 multiplied by 5 equals 45.
Now, our equation is simplified to: 45 + 40.
Finally, we perform the addition: 45 + 40.
45 plus 40 equals 85.
So, the correct logical result of the equation is 85.
Now let’s check our options again:
Option A is 85.
Option B is 75.
Option C is 65.
Therefore, the correct answer is A.
Did you get 85 on your first try?
Many people incorrectly multiply 50 by 5 first, getting 250, and then divide 450 by 250, which leads to a wrong result.
Always remember to work from left to right when dealing with multiplication and division together!
