### Quick Reference (9)

Indices or Powers

A power, or index, is used when we want to multiply a number by itself several times. This leaflet explains the use of indices and states rules which must be used when you want to rewrite expressions involving powers in alternative forms.

Negative and fractional powers

This leaflet explains the use of negative powers and fractional powers.

Negative and fractional powers

This leaflet reminds students how to interpret negative or fractional powers. (Engineering Maths First Aid Kit 2.2)

Negative and fractional powers

Sometimes it is useful to use negative and fractional powers. These are explained in this leaflet.

Powers and roots

This leaflet reminds students about the meaning of powers, square and cube roots. (Engineering Maths First Aid Kit 1.2)

The exponential constant e

The letter e is used in many mathematical calculations to stand for a particular number known as the exponential constant. This leaflet provides information about this important constant, and the related exponential function.

The laws of indices

This leaflet reminds students of the laws used for manipulating indices. (Engineering Maths First Aid Kit 2.1)

The laws of indices

When a number is to be multiplied by itself, a power or index can be used to write this compactly. In this leaflet, we remind you of how this is done, and state a number of rules, or laws, which can be used to simplify expressions involving indices.

### Teach Yourself (1)

### Third Party Resources (3)

biomathtutor

biomathtutor presents students with a filmed bioscience-based scenario and guides them through some of the mathematics they need to understand and grow confident and competent in using routinely. The case-study scenario, covering practical aspects of haematology and microbiology, is presented via a narrated film, 24 min in length, but divided up into short sections. The film tracks the diagnosis and treatment of a student with anaemia and a throat infection and links the clinical findings and diagnoses to 33 interactive questions and relevant maths tutorials. An additional 24 interactive questions cover the same range of basic mathematical concepts presented in similar biological contexts, with a view to reinforcing students' learning.
biomathtutor was developed by Vicki Tariq (University of Central Lancashire), John Heritage and Tom Roper (University of Leeds), Andrew Bond (University of Westminster), Mike Tribe (University of Sussex) and the EBS Trust. It was funded by HEFCE through its National Teaching Fellowship Scheme.
