# Doctor Vs Engineer

An Engineer was unemployed for a long time. He could not find a job so he opened a medical clinic and puts a sign up outside: “Get your treatment for \$500, if not treated get back \$1,000.”

One Doctor thinks this is a good opportunity to earn \$1,000 and goes to his clinic. Doctor: “I have lost taste in my mouth.”

Engineer: “Nurse, please bring medicine from box 22 and put 3 drops in the patient’s mouth.”

Doctor: “This is Gasoline!” Engineer: “Congratulations! You’ve got your taste back. That will be \$500.”

The doctor gets angry and leaves after a few days to recover his money. Doctor: “I lost my memory, I do not remember anything.”

Engineer: “Nurse, please bring medicine from box 22 and put 3 drops in the patient’s mouth.”

Doctor: “But that is Gasoline!” Engineer: “Congratulations! You’ve got your memory back. That will be \$500.”

The doctor gets angry and comes back after a few days. Doctor: “My vision has become weak.”

Engineer: “Well, I don’t have any medicine for this. Take this \$1,000.”

Doctor: “But this is \$500…”

Engineer: “Congratulations! You got your vision back! That will be \$500.”

### Can you find the correct number?

Okay, here comes the challenge.

In the picture below, you will face a math problem, and there are three different possible solutions you can pick from.

Which of the answers do you think is right?

Yes, just too much numbers and you might not even sure where to start. So, let’s see how you can actually solve this tricky math problem.

To arrive at the correct answer, the trick is you honestly just need to use the right order of solving operations—PEMDAS. That is an acronym for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction—and that’s the order that you need to follow.

For the math problem given, what you need to do is to solve the operation in the parentheses first.

18 ÷ 3 x (12 – 4) = ?

12 – 4 = 8.

That will give us 18 ÷ 3 x 8 =?

First, 18 ÷ 3 = 6.

Then, 6 x 8 gives us 48.

Hence, the final answer is 48!
