Help me understand division in modular arithmetic In mathematics, modular arithmetic is a system of arithmetic for integers, where numbers "wrap around" upon reaching a certain value So the point of modular arithmetic is to do our normal arithmetic operations wrap around after reaching a certain value
Arithmetic or Geometric sequence? - Mathematics Stack Exchange Similarly, an arithmetic sequence is one where its elements have a common difference In the case of the harmonic sequence, the difference between its first and second elements is $\frac {1} {2}-1=-\frac {1} {2}$
What is the difference between arithmetic and geometrical series . . . 4 Geometric and arithmetic are two names that are given to different sequences that follow a rather strict pattern for how one term follows from the one before An arithmetic sequence is characterised by the fact that every term is equal to the term before plus some fixed constant, called the difference of the sequence
