Tricky  Math test 18 ÷ 3 (5 - 4 + 1) = ? Solved


Solving tricky Math problems can refresh your brain.
This tricky Math question has gone viral over the internet with many people having their answers as 3 and 12. Some have theirs which are not even near correct. What is your own answer? Well if you have doubts in your answer, then I will clarify you in this article with the correct answer.


18 ÷ 3 (5 - 4 + 1) = ? Solved
Tricky  Math test 18 ÷ 3 (5 - 4 + 1) = ? Solved
The Math test is 18 ÷ 3 (5 - 4 + 1) = ? 
To solve this, all you need to do is to apply the concept of BODMAS OR PEMDAS which I have explained in other blog post with good examples.


We have been using BODMAS since our primary school days but many of us have not understand how to apply it well to solve Math problems.
For example, the "O" in BODMAS stands for Order of operation and not "Of" as some people mistake it. If you still have doubt and want to know more details about BODMAS, then click here.

Solution:

With BODMAS, B stands for bracket meaning we should solve what ever is in the bracket.
So, 5 - 4 + 1
5+ 1 = 6
=6 - 2
= 2. 


Rewriting the question will be as thus:
18 ÷ 3(2)= ?
= 18 ÷ 3 × 2 = ? The "O" in BODMAS means Order of Operation and not "of" as some people mistake it. That's after you solve what is in the bracket, you need to follow a particular order too as you solve ( Divisional, Multiplication, Addition and Subtraction).


So, 18 ÷ 3 × 2 = ?
18 ÷ 3 = 6
Implies 6 ×  2 = ?
Implies 12 = ?.


This means the correct answer is 12 if you follow BODMAS or PEMDAS role.

See screenshot below on my calculator.


If your answer is 3, it means you multiplied before dividing which is wrong.

  1. And you are incorrect: the fact is your error was caused by using a calculator. Now write that problem out as a fraction and try again.

  2. The reason this is wrong--the answer is three-is because brackets are done first (2) and brackets are attached to 3--as opposed to indicating separation with further brackets--forcing 6 as the consequence of those brackets. Therefore the answer is 3. You literally cannot type " 18 / 3 ( " on my calculator app without it being reformatted to " 18 / ( 3 ". Notice that instead of pressing "3(" as your question suggests you were forced to press "3x(". Therefore 3 is the correct answer.
