Introduction
Arithmetic is the elementary branch of mathematics we use daily, such as buying, selling, estimating expenses, and checking bank balances. When we count, we use arithmetic; when we perform the simple operations of addition, subtraction, multiplication, and division, we use principles of arithmetic. Arithmetic is woven into our general interaction with the real world, and as such, it forms the basis of all science, technology, engineering, and business.
Whole numbers are simply the numbers 0, 1, 2, 3, 4,… They include all counting numbers, also known as natural numbers or positive integers (1, 2, 3, 4,…), and zero (0). All whole numbers are integers. However, whole numbers and integers differ because integers include counting numbers (positive integers) and their negatives (negative integers).
