We've got an interesting Japanese math problem for all you math lovers out there! Try it out. And for all others, be cautious while using a calculator to find the answer. You can make a mistake while entering the equation on a calculator. Want to know how? Let me explain!
The Most Common Mistake
Most of you will enter the problem like this on a calculator which would give you a wrong answer!
The Calculators Can't Differentiate
Most calculators will not distinguish between the two division symbols!
The Root Cause of the Mistake
To a Calculator, ÷ Is the Same as / and that is the root cause of the mistake!
The Error
So, Going from Left to Right, 3 Is Mistakenly Divided by 1
That's Why It Gives Wrong Result
That leads to the answer of 3 that is about to be divided by 3.
