Mathematical Conventions

A full-stop rather than a decimal point is used. This is done for technical reasons so when typing your answers you will have to use a full stop. E.g. use 6.7 not 6·7. When hand writing figures you can use a decimal point, i.e. 7·5.

The decimal point symbol is a convention designed to communicate effectively - where it sits, on the line or in the middle, is purely convenience and has no mathematical significance.

Most non-English speaking countries use a comma instead of a point. A German drug house would use 2,5mg rather than 2.5mg.

In most cases a space is used to separate 'thousands' rather than a comma or no space. E.g 2 000 rather than 2000 or 2,000.

 

There should not be a space between numbers and their units . E.g. 2ml, 24cm, 89kg but a space is used where the unit is written in full. E.g. 700 micrograms.

There should always be a zero in front of the decimal point when the number is less than 1. E.g. 0.4, 0.8, 0.9.

The symbol for 'micro' is 'µ' but when hand written may be confused with a 'u' or 'm'. Hence, always write micro. E.g. use 4 microgram rather than 4µg.

Understanding Task Feedback

Once you have entered your answers in to the text fields and clicked on the Done button you will be presented with a feedback window. The information displayed here indicates how well you have done. The original questions are repeated for you to refer to. A correct answer will by indicated by a tick, an incorrect answer indicated by a cross and an unattempted question by a question mark.

In the case of an incorrect or unattempted question the actual answer will appear along side in red text. You will be able to compare the correct answer with the original question.

Macromedia Flash

What is Flash? Flash enables webpages to be made interactive and enhances the users experience with colour, animation and and even sound. Flash has been used quite extensively throughout this course. You do not need to understand Flash and you will be provided with the necessary instructions.

When viewing a Flash 'movie' it is not possible for the user to choose when to go back and review a section. Occasionally this option is offered and is normally marked with a 'Replay' button. You will have the ability to Restart a whole movie once it has ended by clicking on the 'Restart' button.
