## Introduction

Which of the following numbers can be expressed as finite or infinite recurring decimals?

√2; √4; √3; π (Archimedes' constant); 2πr; 1/9; 22/7; φ (golden ratio); e (Euler's number)

Which number set do the recurring decimals belong to?

The whole part and some digits after the decimal place of π (pi) are 3.14159265. Do you notice any kind of period determined by a certain repetition in these digits?

This tutorial focuses on surds - a term originally used to express irrational numbers but that recently has acquired a slightly different meaning. Therefore, we are going to explain the meaning of surds and also the similarity and difference of surds and irrational numbers - which we dealt with in the first chapter of this course.
