Question

Define integers and write the properties of addition and subtraction of integers​

Answer 1

Answer:

Integer Property Addition Subtraction

Commutative Property x + y = y+ x x – y ≠ y – x

Associative Property x + (y + z) = (x + y) +z (x – y) – z ≠ x – (y – z)

Identity Property x + 0 = x =0 + x x – 0 = x ≠ 0 – x

Closure Property x + y ∈ Z x – y ∈ Z

Answer 2

An integer (from the Latin integer meaning "whole") is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 512, and √2 are not.

Commutative Property

addition: x + y = y+ x

subtraction : x – y ≠ y – x
