### What did Sumer develop?

well, my class just finished studying Sumer and Sumerians.
Sumerians developed alot of things. they developed cuneiform which
was the world's first system of writing using pictographs and
symbols. They also developed the wheel which they used for pottery
(potters wheel) and they developed medicines and in math, they
developed a system revolving around the number 60. For example,
there are 60 seconds in a minute and 60 minutes in an hour and
yeah. Oh and the plow, used for farming which increased farm and
food production. Thats all i can remember, but in my opinion, the
most impressive is the writing development.

### Cycle rate per hour on a thermostat?

Cycles Per Hour (CPH) is the number of times the thermostat will
turn the system on and off using 50% of its capacity.
CPH 3 (Gas 90%+ efficiency) the system will turn on and off three
times in one hour using 50% of the systems capacity.
CPH 9 (Electric) the system will turn on and off nine times in one
hour using 50% of the systems capacity.

### What does the word digits mean in math?

A digit in math is a component of a natural number which is less
than the base of the number system you are using. Natural numbers
are all of the non-negative integers, sometimes including zero.
So in the decimal number system, which has a base of 10, a digit
is any number from 0 to 9.
If you are using the binary number system, which has a base of
2, a digit can only be a 0 or a 1.
If you are using the hexadecimal number system, which has a base
of 16, a digit is any number from 0 to 15 (the numbers 10-15 are
generally represented as A, B, C, D, E, F).
If you are using the Sexagesimal number system, which has a base
of 60, a digit is any number from 0 to 59. This is the number
system which the Babylonians used, which is one of the reasons why
we divide an hour into 60 minutes, and a minute into 60 seconds.
This is also why we have 360 degrees to a circle.
