Ratios are an alternative way of expressing fractions. This leaflet will revise ratio calculations

A ratio is a way of comparing two or more similar quantities, by writing two
or more numbers separated by colons. The numbers should be whole numbers, and
should not include units.

This leaflet explains how formulae can be rearranged. (Engineering Maths First Aid Kit 2.11)

The ability to rearrange formulas, or rewrite them in different ways, is an important skills. This leaflet will explain how to rearrange some complex formulas.

This leaflet explains how to expand or remove brackets from an algebraic expression. (Engineering Maths First Aid Kit 2.3)

In order to simplify mathematical expressions, it is frequently necessary to 'remove brackets'. This leaflet explains the rules for replacing bracketed terms, with non-bracketed equivalents.

This leaflet explains how to multiply together two bracketed linear expressions. (Engineering Maths First Aid Kit 2.4)

In this leaflet, we show you the correct procedure for writing expressions of the form (a+b)(c+d) in an alternative form, without brackets.

This volume arose from a conference, 'Addressing the Quantitative Skills Gap: Establishing
and Sustaining Cross-Curricular Mathematical Support in Higher Education', held at the
University of St Andrews in 2007. The aim of that conference, and of this volume of
collected essays, is to explore the logistics and economics of establishing and sustaining
institution-wide mathematics support provision.
We explore a range models for delivering mathematical support accommodating an even
wider range of budgets. Additionally, we identify how universities can call upon their maths
support provision to demonstrate that they are addressing institutional agendas including
quality enhancement, employability and skills, the first year experience, flexible delivery,
retention, and the student learning experience. Looking to the future we note how
mathematics support has broadened from its original focus on the STEM subjects and
discuss how emerging technologies are being exploited for its provision.

Evaluating expressions involving numbers is one of the basic tasks in
arithmetic. But if an expression is complicated then it may not be clear
which part of it should be evaluated first, and so some rules must be
established. There are also rules for calculating with negative numbers.
