This leaflet explains how to add or subtract algebraic fractions. (Engineering Maths First Aid Kit 2.8)

Fractions involving symbols occur frequently. It is necessary to be able to add and subtract them. On this leaflet, we revise how these processes are carried out. An understanding of writing fractions in equivalent forms is necessary.

Matrices 3: This leaflet explains the conditions under which it is possible to add or subtract two matrices. It explains how to perform addition and subtraction when this is possible. It also explains how a matrix can be multiplied by a number. There is an accompanying video tutorial.

A report on an audit of 13 Irish institutions providing mathematics learning support and the various structure/types of mathematics support they offer conducted by CEMTL and compiled by Olivia Gill, John O'Donoghue and Paddy Johnson.

This paper by Shazia Ahmed, Jane Joy, and Deirdre Moriarty describes the evaluation of a formula card for nursing students created at the University of Glasgow. (2013) MSOR Connections 13(1), 41-44. DOI: 10.11120/msor.2013.13010041

MATLAB is the chosen simulation environment that is used throughout the Department of Electronic and Electrical Engineering. MATLAB is used by the students at several levels. It is used in earlier years as an 'Engineering' calculator that is useful for scientific calculations and visualisation particularly for complex analysis. As the course develops MATLAB becomes invaluable for investigating the time-frequency characterisation of signals and systems. MATLAB also gives the students an environment that allows them to write programming code in a 'C' like format. Finally MATLAB facilitates greater contextual teaching and problem based learning, which has become increasingly important in current Electronic and Electrical Engineering.

At the Times Higher Awards ceremony
on 24th November 2011, it was
announced that Loughborough and
Coventry Universities had won the
award for Outstanding Support for
Students, in recognition of the work
of sigma, Centre for Excellence in
University-wide mathematics and
statistics support.
Whilst sigma at Coventry and Loughborough Universities received the award, the real winner was mathematics and statistics support across the country. In this booklet,
we outline how sigma's work has contributed to the growing recognition of the importance of mathematics and statistics support and to the development of a national and international community of practitioners. Authors : Ciaran Mac an Bhaird and Duncan Lawson

Arithmetic and geometric progressions are particular types of sequences of numbers which occur frequently in business calculations. This leaflet explains these terms, and shows how the sums of these sequences can be found.

This unit introduces sequences and series, and gives some simple examples
of each. It also explores particular types of sequence known as arithmetic
progressions (APs) and geometric progressions (GPs), and the corresponding
series.
