Calculations involving several operations can also be carried out in stages. One way to do this is to use the '=' key part way through the calculation. You can also use the calculator's memory.

To perform a simple arithmetic calculation:

1. Enter the first number in the calculation (for example '123') using one of the following methods:

• Using your computer keyboard's numeric keypad, which (if you have one) is on the right of your computer keyboard. Check to see whether the Num Lock indicator light is on and if it is not press the NUM LOCK key.

One of the most fascinating and productive ways of using your computer for study is connecting to the internet to access the extensive amount of information available on the web. Such a diverse range of material brings its own challenges.

It's therefore useful to know how to search effectively. Have a look at our Web Guide (accessed 8 November 2006).

The BBC's Webwise online course (accessed 8 November 2006) will also help you become a confident web user.

We can see that Philip knows what a sentence is because he writes some perfectly good ones. For example:

In many ways going into urban life from the countryside was beneficial to woman of the upperclass.

This sentence begins with a capital letter and ends with a full stop. It has a subject (urban life) and a main verb (was). As any sentence is, it is a self-contained ‘unit of meaning’. It m

Of all aspects of studying, writing is probably the most challenging. That is because when you write down an account of your ideas for other people to read you have to explain yourself particularly carefully. You can't make the mental leaps you do when you are in conversation with others or thinking about something for yourself. To make your meaning clear, using only words on a page, you have to work out exactly what you think about the subject. You come to understand it for yourself i

Mind–body dualism has been a pervasive problem since the seventeenth century. One consequence of this dualism is the way in which bodies have been treated in psychology. They have generally either been ignored or reduced to biology. However, our bodies are much more than simply biology; at the very least, they are the interface between the individual and the social world or, more radically, they are inherently social objects. There is growing recognition of the interaction between our bodie

As we saw in Section 1, ‘medical’ approaches to some psychological conditions have focused on biochemistry and the use of corresponding drug treatments. Very little research of this kind has been applied to dyslexia. However, emerging evidence suggests that there may be a biochemical contribution involving abnormal metabolism of highly unsaturated fatty acids (HUFA) – essential substances that play a key role in brain development and the maintenance of normal brain function.

What did you write for ‘normal’ eyesight? The ability to see clearly without glasses? It is unlikely that you wrote down short- or long-sightedness as an example of ‘normal’ eyesight, even though they are very common. However, they are not seen as ‘normal’ because having to wear glasses is perceived as a limitation or even a form of disability. This relates to one of several so-called ‘medical models’ of normality, which centre on the idea of uniformity of physical and psychol

If I have seen farther than others, it is because I was standing on the shoulders of giants.

Sir Isaac Newton (Letter to Robert Hooke, 1676)

At the foreground of this final part of the course is one of its more important themes – that knowledge is something held, developed and perpetuated both by and in the context of communities, societies and cultures. Newton's declaration to Hooke (abo

To understand science, it is important that we appreciate the contexts in which discoveries are made or suppressed. We can see from the account on the previous page that human understanding of the universe has changed significantly over time. The social and political climate in which scientists work has always had a profound influence on what can and cannot be said, done, published or even postulated as worthy of further investigation.

Between 1995 and 2012, The Open University trained just over 8000 teaching assistants through its course E111 Supporting learning in primary schools and its now discontinued Specialist Teacher Assistant course. Most were women and many were mothers; a very small percentage were male. Heather Wakefield (2003), head of local government liaison at UNISON, emphasises the link between caring work in the public sector and the recruitment of a predominantly female paraprofessional workforce.

Let us leave the emotive word ‘sexism’ to one side for a moment and look at what Beveridge actually said about the place of women in his scheme and the kind of reasoning he used. He gave considerable attention to the position of married women:

Margaret was in her thirties when she learnt she had breast cancer. Some three years later, after the removal of the affected breast, she was leading a very busy life working full-time at the Open University, studying part-time for an OU degree and running a family. Fitness activities such as jogging and various sports had become very important in her life. She was also very involved in cancer research fundraising activities. She described the impact of her brush with death in this way:
