19:00 hours

24 hours in a day


1900 hours, subtract 12 hours - 7 p.m.

Oh cool! Thanks Beth :-D

hometown is a military town :wink:

It works out beautifully. We have one ex-marine on the payroll, and 45 civilians. He starts at 0600 (six a.m.) and usually ends around 1800 to 2000 hours. Subtract the little one from the big one, and you've got the hours worked. Now consider the rest of them. Start at 6:00 and end at 5:30. Okay, 6 in the morning, 5 1/2 in the afternoon, so 6 + 5 1/2 is 11 1/2. Sometimes they work so many or so few hours, you're not sure if the shut down in the a.m. or p.m. and they sure won't put it on the time sheet - we don't use time cards.

On the other hand:

The radio station at an air force base announced the time as "0200. That's 2 a.m. for civilians on base. For you sailors, it's 4 bells. And if their are any marines listening, the big hand is on 12, and the little hand is on 2." Our marine is better than that of course. He ties his own shoes and everything.

In Europe we use the term as well to distinguish between
morning and afternoon. 1:00 o'clock is 1:00 am,
however 1:00 pm is 13:00 hours. After noon time, we
just continue counting until we reach 24:00 hours.

I always remove the 1 and subtract 2 to get the time I'm used to.

Betcha you count hooves and divide by 4 to find out how many cows ya got, too.

Well, it's easier to subtract 2 than it is to subtract something from 12.

Neener.

You don't want to know how I add 9's.

Add 10 and subtract 1?

I remember trying to explain this, to me, extremely obvious concept to a friend in 3rd grade or something... it didn't go very well...

Yes! I remember trying to explain it to my third grade teacher. I must not have articulated it very well at the time -- she told me I was doing it wrong.

I've never understood the point of taking extra steps when doing basic math.

Add/subtract/multiply/divide - just do the math <as an 11 year old said to me on the weekend>

My Dear Aunt Sally used to say 'Multiply, Divide, Add, Subtract', in that order. Mostly we kept Dear Aunt Sally in the attic.

Adding 9s, FreeDuck? I used to be an expert at casting out the 9s, but lost it all when they bought me a calculator.

You have an Aunt Sally too?

That was the sticking point in explaining it, too. To me, it's not extra steps, it's a shortcut.

To me too. I wasn't sure if she was talking about our method as extra steps or doing it the traditional way as extra steps. I guess it seems to me like certain numbers are easier to work with and take less brain operations, even if, on the surface, it looks like an extra step is required.

This is all very interesting. It seems that people calculate things in their own different and special way.
I find Beths way the easiest for me.

Yeah, that's how I do my 9s as well. Piece of cake ;-)

I bet this is a elementary school trick?New Math
