There is a right way to think about equations and there is a wrong way to think about equations. Let us not speak of the wrong way…

The equations I have in mind are those equations written in the form

f(x)=g(x),

where the aim is to find all the real numbers x that ‘satisfy’ the equation.

We aren’t always taught the logic behind solving equations. The first thing to say is that many of us are trained to believe that this ‘=‘ means the ‘the answer is’. This is not what equals means. This may have happened to us because while young children our textbooks had stuff like

2+6=\dots

written in them… the ‘answer’ of course being eight and the = sign almost suggests that we have to ‘do something’ to 2+6. Of course, this is not what equals means, and while the pupil who writes

2+6=8

is correct, the pupil who writes e.g.

2+6=11-3,

has written a statement just as true as 2+6=8.

Week 2

In Week 2 we looked at Decimals — including long multiplication and division — Ratio & Proportion and approximation. We have just began to look at percentages.

Week 3

We will finish off the section on percentages and then look at error. This will conclude our study of the Assessment 1 material. After this we will look at tax and interest.

Introduction

In Ireland at least, we first encounter fractions at age 6-8. At this age, because of our maturity, while we might be capable of some conceptional understanding, by and large we are doing things by rote and, for example, multiplying fractions is just something that we do without ever questioning why fractions multiply together like that. This piece is aimed at second and third level students who want to understand why the ‘calculus’ of fractions is like it is.

Mathematicians can in a rigorous way, write down what a fraction is… this piece is pitched somewhere in between these constructions — perhaps seen in an undergraduate mathematics degree — and the presentation of fractions presented in primary school. It is closer in spirit to a rigorous approach but makes no claims at absolute rigour (indeed it will make no attempt at rigour in places). The facts are real number axioms.

Defining Fractions

We will define fractions in terms of integers and multiplication.

To get the integers we first define the natural numbers.

Definition 1: Natural Numbers

The set of natural numbers is the set of counting numbers

\mathbb{N}=0,1,2,3,4,\dots,

together with the operations of addition (+) and multiplication \times.

Manuals

The manuals are available in the Reprographic/Copy Centre. You will need these notes for next week.

Week 1

We studied basic arithmetic, in particular we looked at the various number systems and the arithmetic of fractions in particular.

Week 2

In Week 2 we will look at Decimals — including long multiplication and division — Ratio & Proportion and probably percentages too.

Tutorials

Tutorials start properly in Week 2. See your timetable.
