Maths Exams: The Results

Now that the exam results are through, the SQA have released their official marking instructions for all the maths exams set in 2008. All levels can be viewed/downloaded here. The Grade Boundaries for all subjects at all levels is also available here.

The poll in the sidebar has been updated to ask ‘what grade did you get?’, which should make an interesting comparison to the poll asked before the results were sent asking ‘what grade do you think you’ll get?’ (which can be seen below)

Maths Teaser: The Father of Algebra

No, it’s not Mr Stewart.Parthenon

Diophantus was a Greek mathematician who lived in the third century. He was one of the first mathematicians to use algebraic symbols.

Most of what is known about Diophantus’s life comes from an algebraic riddle from around the early sixth century. Stated simply, it says:

Diophantus’s youth lasted one sixth of his life. He grew a beard after one twelfth more. After one seventh more of his life, he married. Five years later, he and his wife had a son. The son lived exactly one half as long as his father, and Diophantus died four years after his son.

My question is: How many years did Diophantus live? (show some working please!)
