+===== Numeric Observations =====
+When dividing two quantities, the quotient and the remainder have different units.   For example, 10 apples divided by 3 apples is 3, but the remainder is 1 apple.  Note that the quotient unit changed.
+The units may be different too.  Consider calculating the quotient and remainder of 10 meters in 3 seconds.
+A = 10 meters
+B = 3 seconds
+Q = floor(A / B)
+R = A % B
+This maintains the identity A = Q * B + R.  Thus:
+Q = 3 meters/second
+R = 1 meter
+===== Taylor Series =====
+The Taylor Series for the exponential function diverges quickly if less than 100 terms are used.  These terms tend to have enormous numerators and denominators.   The numerator is usually x^100, and the denominator is 100!.   Floating point math is not suited to represent these values as the number of terms exceeds 100ish.
