Numbers are used to specify a quantity or amount. For example, people give their ages as a number of years: â€˜I am 51 years oldâ€™ or â€˜I am five and a halfâ€™. Votes in elections may be described in thousands. Temperatures are measured in positive and negative degrees Celsius. Numbers smaller than one may be expressed as fractions or decimals. This section considers whole numbers, decimals, fractions and negative numbers and reminds you of the essence of a number â€“ how â€˜bigâ€™ it is.

Counting By Two Song
This animated video will help children learn to count by twos. The lyrics repeat themselves several times. The monkey characters count to 100 while the numbers are displayed on the screen. Some of the lyrics include "We're gonna count by two's. Me and you. All numbers will be even. That's just what we do".  (02:53)

Suppose you have less than one of any particular unit: how would you represent that using the decimal system?

Well, we've already seen that decimal numbers rely on a positional system, in which values get smaller by factors of ten as you read from left to right. If we continue doing this, then the number to the right of a single unit represents tenths of that unit. A decimal point is then used to mark the boundary between the whole units and tenths of that unit.

The notions of a final vocabulary and that of ideology are closely related. Anthony Giddens defined ideology as â€˜shared ideas or beliefs which serve to justify the interests of dominant groupsâ€™ (Giddens, 2006, p. 1020). There are all sorts of problems with this definition. One difficulty, for example, is that ideas and beliefs, if they have any kind of existence, are hidden away and have to be inferred by what people do and say. Another difficulty surrounds exactly how these things can be

If you explore all the resources and activities in this course, you might need to allow between two and nine hours to complete it.

Before you read this guide, why not use the self-assessment questions on the screens to rate your current level of knowledge?

Print or save these questions and for each question, mark the most appropriate number on the scale. When you have finished, you can review your answers. A score of three or less might indicate a gap in your knowledge or u

The formulas for speed, distance and time are all examples of mathematical models. Here, you should bear in mind that such models stress some aspects of travelling but ignore others. Building a mathematical model involves making some assumptions, and usually this involves disregarding those inconvenient aspects of real-world events which can not easily be fitted into a mathematical description.

Take, for example, the model s = d/t used to calculate speed. Dividing a

One way to find what you are looking for on the Web is to start from sites that you know are likely to have useful 'links' on them, like the main Open University pages or the Open University Library pages. These opening pages are known as home pages and are a bit like the contents page of a book. The home page usually gives you some information about the content of the website, often with links to other pages of information held on that site and on sites elsewhere. By clicking on a link â€“ w

Even the simplest organisms can detect and respond to events in their ever-changing environment. Similarly, within a multicellular organism, cells are surrounded by an extracellular environment from which signals are received and responded to. Extracellular events are decoded and transmitted to relevant parts of individual cells by way of a series of activation/deactivation steps involving many intracellular molecules. This relay of information along molecular pathways is called signal tra

Automation of Deck Bridge Representations
The bridge deck has a apparent simple shape, but it is the result of an adequate combination of two longitudinal geometric components: the deck shape evolution along de longitudinal section the layout of the road, that acts in simultaneous over a cross section, defining the deck exact shape. A geometric modelling computer programme was developed for box girder decks, allowing the generation of cross sections along the deck, defined with correct shape and location. In the elaboration of the deck

RES.21W-01 Angles (MIT)
Angles is an annual online magazine of exemplary writing by MIT students. All of the works published in Angles since its first edition in 2008 were written by students in the introductory writing courses. These courses, designated as CI-HW (Communications-Intensive Humanities Writing) subjects, bring together students who love to write, students who struggle with writing, students who thrive in seminar-style classes, and students who just want a chance to develop their English skills. These stud

7.2 Drafting reports

As you may remember from Activity 3, the three general principles of a report (whether it is of a social sciences investigation or a scientific experiment) are:

• How was it done?

• What does it mean?
