Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

Comment recorded on the 24 May 'Starter of the Day' page by Ruth Seward, Hagley Park Sports College:

"Find the starters wonderful; students enjoy them and often want to use the idea generated by the starter in other parts of the lesson. Keep up the good work"

Comment recorded on the 28 May 'Starter of the Day' page by L Smith, Colwyn Bay:

"An absolutely brilliant resource. Only recently been discovered but is used daily with all my classes. It is particularly useful when things can be saved for further use. Thank you!"

Each month a newsletter is published containing details of the new additions to the Transum website and a new puzzle of the month.

The newsletter is then duplicated as a podcast which is available on the major delivery networks. You can listen to the podcast while you are commuting, exercising or relaxing.

Transum breaking news is available on Twitter @Transum and if that's not enough there is also a Transum Facebook page.

#### Tower of Hanoi

Move the pieces of the tower from one place to another in the minimum number of moves. This puzzle was invented in 1883 but is still as captivating today as it was all those years ago.

There are answers to this exercise but they are available in this space to teachers, tutors and parents who have logged in to their Transum subscription on this computer.

A Transum subscription unlocks the answers to the online exercises, quizzes and puzzles. It also provides the teacher with access to quality external links on each of the Transum Topic pages and the facility to add to the collection themselves.

Subscribers can manage class lists, lesson plans and assessment data in the Class Admin application and have access to reports of the Transum Trophies earned by class members.

## Go Maths

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.

## Common Units

### Digital Units of Information

Untitled 1

These digital 'units of information' describe the capacity of standard data storage. You may have come across them when reading about the specifications of a computer or the speed of a wifi connection.

The basic unit is the byte (equal to eight bits) and is the amound of storage needed to store one character (a letter, punctuation mark or number).

The SI prefixes use powers of ten nearest the multiples of ten power of two of the binary values. The SI units make calculations much easier to do mentally.

Symbol Name SI value Binary value Size difference
B byte 8 bits 8 bits
kB kilobyte 103 = 1000 bytes 210 = 1024 bytes 2.40%
MB megabyte 106 bytes 220 bytes 4.86%
GB gigabyte 109 bytes 230 bytes 7.37%
TB terabyte 1012 bytes 240 bytes 9.95%
PB petabyte 1015 bytes 250 bytes 12.59%
EB exabyte 1018 bytes 260 bytes 15.29%
ZB zettabyte 1021 bytes 270 bytes 18.06%
YB yottabyte 1024 bytes 280 bytes 20.89%
