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 3 October 'Starter of the Day' page by Mrs Johnstone, 7Je:

"I think this is a brilliant website as all the students enjoy doing the puzzles and it is a brilliant way to start a lesson."

Comment recorded on the 7 December 'Starter of the Day' page by Cathryn Aldridge, Pells Primary:

"I use Starter of the Day as a registration and warm-up activity for my Year 6 class. The range of questioning provided is excellent as are some of the images.
I rate this site as a 5!"

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

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%
