Satellite, you should have asked her if she knew how to subtract time. There's a procedure for that.

OpenStudy (anonymous):

hello numbers!

OpenStudy (anonymous):

really? i don't know it.

OpenStudy (anonymous):

hello statellite!

OpenStudy (anonymous):

nice to see you again

hero (hero):

\[6:00 - 0:40 = 5:60 - 0:40 = 5:20\]

hero (hero):

It's kinda like the borrowing method for subtraction

except this is with time and minutes only go up to 60

OpenStudy (anonymous):

Same here! Thanks hero and thanks satellite

hero (hero):

@Satellite73 seems to think that demonstrating the methods behind mathematical procedures is beneath him.
