In this chapter, we'll make sure your skills are firmly set. We'll take another look at the kinds of numbers we have worked with in all previous chapters.

We'll work. Mathematicians classify numbers into types or number systems. Numbers that can be written as fractions a/b, where a is an integer and b is a natural number, are called rational numbers.

Irrational numbers and rational numbers are two distinct classifications — a rational number. numbers in maths. Sections include fractions, decimals, number types, money, ratios, and factors.
