Question

define addition and multiplication modulo give two examples of each​

Answer 1

Answer:

Addition modulo. ... When a and b are two integers such that a–b is divisible by a fixed positive integer m, then we have a≡b(modm). This is read as a is concurrent to b (modm). Thus,a≡b(modm) if and only if a–b is divisible by m.

Addition (usually signified by the plus symbol "+") is one of the four basic operations of arithmetic; the others are subtraction, multiplication and division. The addition of two whole numbers is the total amount of those values combined.

Example: 5 + 11 + 3 = 19 is an addition. Drag the numbers to the two blue boxes see how addition works: Drag the numerals to the blue boxes.

In mathematics, modular arithmetic is a system of arithmetic for integers, where numbers "wrap around" when reaching a certain value, called the modulus. The modern approach to modular arithmetic was developed by Carl Friedrich Gauss in his book Disquisitiones Arithmeticae, published in 1801

example, 2*3 mod 5 = 1. This means that 2 and 3 are also multiplicative inverses of one another mod 5. Division itself is not something that is defined.
