Do you have any Logical/Proper Explanation?


You must be thinking that the answer to the above equation 29 – 1 = 28, right? But let us tell you that it’s not 1 in the above picture, it’s alphabet I and because your brain is conditioned to read the numbers in a mathematical equation so you must be thinking it’s 1. Now, you will be thinking that how anyone can subtract an alphabet from a number, it’s possible if you expand your vision and consider other scenarios.

If you still aren’t able to get this, let us help you with that. All you need to do is to imagine number 29 in Roman digits which turns out to be XXIX. Now, it’s all pretty easy, isn’t it? The equation will become XXIX – I and if you take I from the roman number XXIX, it turns out to be XXX which is basically 30 when converted back from Roman numbers. Hence, it becomes:



29 – I = 30
