Arithmetic is the oldest and most basic branch of mathematics — the one we all start learning as children. It deals with numbers and the simple operations we perform on them: addition, subtraction, multiplication, and division.
At its core, arithmetic answers questions like:
How many?
How much more or less?
What is the total?
How do we share or distribute evenly?
Natural and Real Numbers
Arithmetic begins with natural numbers (1, 2, 3, and so on), then expands to include zero, negative numbers, fractions, decimals, and irrational numbers like √2 or π. Together, these form the real numbers — a concept that allows us to represent almost every quantity in everyday life.
Applications
Arithmetic is everywhere: in shopping, cooking, budgeting, sports scores, and timekeeping. It’s the basis for all other areas of mathematics, because before we can explore patterns or relationships, we must understand the behavior of numbers themselves.
