In this article, we present two methods for finding the modular inverse in case it exists, and one method for finding the modular inverse for all numbers in linear time. Finding the Modular Inverse using Extended Euclidean algorithm These notes are based on a 2-week course that I taught for high school students at the Texas State Honors Summer Math Camp. All of the students in my class had taken elementary number theory at the camp, so I have assumed in these notes that readers are familiar with the integers mod n as well as the units mod n.
Aug 06, 2005 · Modular arithmetic is a notation and set of mathematics that were first introduced by Carl Friedrich Gauss. The major insight is that equations can fruitfully be analyzed from the perspective of remainders. Standard equations use the ' = ' sign. Modular arithmetic uses the ' ≡ ' sign.

The first project uses modular arithmetic or clock arithmetic. Modular arithmetic is a system of arithmetic for integers, where numbers wrap around after they reach a certain value, which is called the modulus. Carl Friedrich Gauss wrote about modular arithmetic in his book, Disquisitiones Arithmeticae, published in 1801. Modular arithmetic is ...

May 24, 2019 · By the same logic, the last two digits must be only pertinent to powers of 19. Essentially, we will be finding the remainder of the value when divided by a hundred, which is what the last two digits would give us. This is where modular arithmetic comes in. We can simplify the problem into a simple arithmetic equation:

the remainders when dividing by 7, then the equation reads 3 + 4 = 0. An arithmetic that uses remainders is referred to as a modular arithmetic. In a system governed by remainders when dividing by 7, or modulo 7, the numbers 3, 10, 17, 24, . . . all become the same number, and “3” would be written to represent this entire class of numbers.

In some sense, modular arithmetic is easier than integer arithmetic because there are only finitely many elements, so to find a solution to a problem you can always try every possbility. We now have a good definition for division: $$x$$ divided by $$y$$ is $$x$$ multiplied by $$y^{-1}$$ if the inverse of $$y$$ exists, otherwise the answer is ...

Introduction to Modular Arithmetic: Clock Math Ryan Felix; SUPER M February 13, 2013 1 Introduction High school mathematics often limits itself to studying the real numbers and the usual arithmetic it entails. However, there are various other number systems one can study, some with very di erent types of operations.
Modular arithmetic is sometimes called clock arithmetic, since analog clocks wrap around times past 12, meaning they work on a modulus of 12. If the hour hand of a clock currently points to 8, then in 5 hours it will point to 1. While 8 + 5 = 13, the clock wraps around after 12, so all times can be thought of as modulus 12.
