What is 01:05AM - 2:06
What do you think it is?
What have you tried so far? Any guesses?
10:59PM
So they are trying to see if you can subtract with time?
That is what I think he means
Well, what are the optional choices? If there are any
The difference between 01:05AM and 2:06AM/PM? I don't know. This is my best guess on the question
1:05AM - 2hrs and 6min
That will be 10:59PM
the difference is a mathematical term for subtraction
So yes we are subtracting time here
We have a starting time of 1:05am and we need to go back 2hrs and 6 minutes
Can you show me how to do it with "paper and pencil"
Ok. Lets do the hours first \[1:05AM - 2\] is 11:05AM
Then you take away 6 \[11:05PM-00:06\] \[10:59PM\]

Nice drawing ;)
hmm it works for easier ones... but what about when you get into 24 hour time and you have seconds.
@Ahsome is correct, but I wanted to show a graphic drawing as the "question asker" needs to know how to write this down on paper.
In graphing terms
So @CoconutJJ when you want to solve this problem you should just draw a clock
1am 5pm 6pm all the times.
problem with that is when the number of hours is greater than 24
Can you give example?
Remember that 24hrs is 1 full day. So say you had 5pm - 24hrs You would just go back a FULL DAY and go to 5pm yesterday
yea but what about this 23:09:56PM - 78hrs:53min:23secs
23:09:56PM - 78hrs:53min:23secs So our starting time is 23hours: 09minutes: 56seconds we must subtract 78hrs: 53minutes:23seconds from our starting time Note: 78hrs is 3days and 6hrs
So lets start with the seconds What 56 - 23?
I'm in search of some algorithmic way. like normal "vertical" subtract
33
33 is our seconds now lets move on to minutes 09minutes minus 53minutes Now we cannot subtract 53minutes from 09minutes. We must borrow 1hour from 23. 23-1 = 22 1:09minutes - 53minutes = ?
16min
Sorry I disappeared So now we have 22hrs 16min and 33seconds
We need to subtract 78hrs from 22hrs
This is sort of weird as you are basically subtracting 3FULL days which will bring it right back to 22hrs. Just 3 days back. But then we will also have to subtract 6hrs from 22hrs What is 22 - 6 ?
It seems that you might be afk so I will answer this for you. 22 - 6 = 16
Our final answer is 16hrs 16min and 33 seconds
16hrs 16min 33seconds Remember this is 3days 6hrs 53min and 23seconds back from the starting point of 23hrs 09min and 56seconds
If you have any more questions just let me know :)
