Modular arithmetic before C.F. Gauss: Systematizations and discussions on remainder problems in 18th-century Germany Maarten Bullynck1 Interdisziplinäres Zentrum für Wissenschafts- und Technikgeschichte, Bergische Universität Wuppertal, Gaussstraße 20, 42119 Wuppertal, Germany Available online 5 November 2008 Abstract Remainder problems have a long tradition and were …... implies that there exists solutions to the equations ax d mod (b) and bx d mod ( a ) by reducing the equations modulo b or a , respectively. This is why only numbers relative prime …

**Modular Arithmetic continued Math**

modular arithmetic problems will usually be simpliﬁed to a number in this range. Example. (a) What are the equivalence classes under the relation of congruence mod 3?... Modular arithmetic is sometimes called clock arithmetic, because the rules in modular arithmetic are the same rules that apply to telling the time. In a clock, there are 12 hours, and once you get

**Divisibility_Solutions.pdf Prime Number Numbers**

Modulo a Prime Number We have seen that modular arithmetic can both be easier than normal arithmetic (in how powers behave), and more diﬃcult (in that we can’t always divide). But when n is a prime number, then modular arithmetic keeps many of the nice properties we are used to with whole numbers. (Recall that a prime number is a whole number, greater than or equal to 2, whose only …... In modern terms, this type of problem leads to two linear equations to be solved in integers, but involving three unknowns. 8 The problem, if fractional and negative solutions are excluded, can have a finite number of solutions, an infinite number of solutions, or no solutions.

### In our present setting of modular arithmetic, can we be sure that x has an inverse mod m , and if so, is it unique (modulo m ) and can we compute it? As a ﬁrst example, take x = 8 and m = 15.

- In our present setting of modular arithmetic, can we be sure that x has an inverse mod m , and if so, is it unique (modulo m ) and can we compute it? As a ﬁrst example, take x = 8 and m = 15.
- Using all the former substitutions we have x=12-y,x>y,,, 12-yy or y>6 Both apples and bananas were bought, so y is between 1 and 5 from earlier solutions we have that y=4b-32 therefore y is divisible by 4 from information in the third line we conclude that y=4 So there are 4 bananas bought.
