**I am emailing a link of this to everyone on the class list every week. If you are not receiving these emails or want to have them sent to another email address feel free to email me at jpmccarthymaths@gmail.com and I will add you to the mailing list.**

## 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:

- DCOM1 Group A: Wednesday 09:00 in C212 (with Len O’Driscoll) and Thursday 09:00 in B185 (with Frances Wood)
- DCOM1 Group B with myself: Monday 12:00 in F1. 3 and Thursday 12:00 in B165
- DNET1 with myself: Monday 14:00 in B248 and Wednesday 15:00 in C212
- WEB1 with Ben O’Shaugnessy: Monday 16:00 in C212 and Thursday 15:00 in E7

## Assessment 1

Assessment 1 will be on the Wednesday of Week 4. Keep an eye on your CIT Blackboard for the latest and definitive assessment information.

## Academic Learning Centre

I would urge anyone having any problems with material that isn’t being addressed in the tutorials to use the Academic Learning Centre. As you can see the timetable is quite generous. You will get best results if you come to the helpers there with *specific *questions.

## Study

Please feel free to ask me questions about the exercises via email or even better on this webpage.

## Math.Stack Exchange

If you find yourself stuck and for some reason feel unable to ask me the question you could do worse than go to the excellent site math.stackexchange.com. If you are nice and polite, and show due deference to these principles you will find that your questions are answered promptly. For example this question regarding infinite decimals.

## Maple Online & Wolfram Alpha

If you are subscribed to CIT MathsOnline you will have free access to the mathematical software package *Maple:*

**Self-enrolment for Maths Online**

1. Log into Blackboard Learn

2. Click on the Courses tab button at the top of the screen. Go to Course Search and type Maths Online in the box.

3. Once you’ve found the course, click on the action link button next to the course and click on Enrol. This should take you to the Self Enrolment page.

4. Your Access Code is mathsonline (lower case, no spaces).

5. After you’ve finished click Submit. You should now see a message that says your enrolment was successful.

Once you’ve enrolled, you can download Maple by selecting the *Mathematical Software* tab in the left hand column and following the instructions under the Maple item.

I myself am not a *Maple *expert but ‘grew up’ with another mathematical software package *Mathematica*. *Mathematica *powers the “computational knowledge engine” WolframAlpha. Go on ask it a question!

## Calculators

Although Assessment 1 is to be taken without the use of calculators, subsequent assessments will have no such ban. Please note the following taken from the CIT code of conduct for CIT examination candidates:

“*Where a pocket calculator is used it must be silent, self-powered and non-programmable. *

*It may not be passed from one candidate to another. Instructions for its use may not be *

*brought into the Examination Hall. *

*The term ‘programmable’ includes any calculator that is capable of storing a sequence of *

*keystrokes that can be retrieved after the calculator is turned off or powers itself off. Note that the *

*capacity to recall, edit and replay previously executed calculations does not render a calculator *

*programmable, provided that this replay memory is automatically cleared when the calculator is *

*powered off. Also, the facility to store numbers in one or more memory locations does not render *

*a calculator programmable. *

*Calculators with any of the following mathematical features are prohibited: *

*• Graph plotting *

*• Equation solving *

*• Symbolic algebraic manipulation *

**• Numerical integration**

*• Numerical differentiation *

*• Matrix calculations *

*Calculators with any of the following features are prohibited *

*• Data Banks *

*• Dictionaries *

*• Language translators *

*• Text retrieval *

*• Capability of remote communication*“
