Subtract the following military times: 1100 - 0530 =

I’ll do an example problem, and I challenge you to do this on your own!

If the example is find the difference between 0645 and 1200, we know that there are 60 minutes in an hour, so 0645 is 6 hours and 45 minutes or 6+45/60=6+3/4 of an hour by dividing both the numerator and denominator by 15. Finding that in minutes, we have 60*6+45=360+45=395 minutes due to that you add 60 minutes for every hour.

1200 is just noon, but that’s 12 hours, so we can convert that into minutes - 60*12=720

Finding the difference, we get

720
-395
due to that -395=-400+5, so 720-400=320 and 320+5=325
325

Converting them back into hours, we get 325/60=5+25/60, which is 5 60 minute increments (5 hours) and 25 minutes, or 0525

Good luck, and feel free to ask any further questions!

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
