Since practically everyone can read the time off a
phone easy, I'll tell you about regular clock time as
short as possible.

Almost every clock we use has numbers 1-12 on it,
unless you're using 24 hour format, then it's 00-23.
So imagine 12 on top, 3 on right, 6 bottom, 9 left, and
every other number spaced in between.

The short hand always says the number it's pointing.
The long hand is always 5 times the number it's pointing.
The short hand does every hour and the long hand
does every part of the hour in between (between 0-60).
Example: short hand at 3, long hand at 3...(3 and 3*5)
or 3:15 (quarter past).
Example 2: short hand a little past 7, long hand between
9 and 10...(7 and 9*5 or 10*5), or between 7:45 and 7:50.
The tiny marks between 9 and 10 specify the minutes
(46, 47, 48, 49).

Last thing. How do you know it's AM or PM? Read
the time and look outside the window or anything
that tells you what's specifically happening. With that,
please look at pic related and tell me what time is it.

For multiplication, I recommend looking at the
Trachtenberg method as it's found online as a PDF.
No more times tables with this one!
