I am working on the file "Clock Arithmetic.ipynb".
The first task is:
Try doing a number of these yourself.  Guess the answer before hitting the Shift-Enter key.
You may find your first years of formal schooling did not emphasize cyclic arithmetic, except in the two most common forms, of telling time and scheduling appointments.  We understand both the 24 hour day, and the 365 day year, comprise a modulus such that we're always talking about our degree of offset into each one.  Adding hours or days, per a timedelta object, keeps us within the scope of some calendar.
The unit circle of 360 degrees, or 2 pi radians, is also treated in a clock-like fashion.  Going around thousands of degrees from some present position, never takes us beyond 360.  We're confined to a finite domain.  Cyclic phenomena more generally are accommodated by our clock arithmetic, of complex numbers, of e to imaginary powers.
There's a kind of "closure" in this picture, which might be resonating with you by now, as one of those properties of a group.  Will we find groups in this Chapter?  You bet.  Groups also enjoy the symmetry of a circle in that each member is paired with another "180 degrees opposite" although sometimes the inverse might be the same as the self.
Again, we call this "clock arithmetic" because even if we say "20 hours from now", or "30 hours ago" we'll still be somewhere on the circle marked out into 12 intervals, each representing one hour.  The yearly calendar is likewise a kind of modulus.  No matter how many days we add, we're still somewhere between 0 and 365 days into some year.
We also call it "modulo arithmetic" meaning the computations are always vis-a-vis some fixed modulus.  This word "modulus" is our inspiration for the M-numbers coded below.
A Class for M-numbers
Lets build a class, the instances of which will multiply and add per some fixed modulus, meaning we're always factoring out the modulus and keeping the remainder.
Can you write Python program for it?
