Damiano Testa - MA246 Number Theory
** MA246 Number Theory
by Damiano Testa (tests Friday 11am, Room MS.02)**

There are four 50-minute tests, at 11am on Fridays of weeks 2-5, plus a final exam closer to the end of term. Each week you will have a workbook
covering the material that will be the subject of the next in-class test. I will post the solutions to the workbooks on the Thursday before each test, so
you can compare your solutions with the ones available online. The final exam will cover material from all 5 workbooks (Workbook 5 will only be covered
by the final exam, and not by any of the tests).
You can find the workbooks on this webpage, and you can also buy for £3 printed versions of them from the General Office.

Workbook 0, intended as practice/review for the course.
Solutions available here shortly after the meeting on Friday April 26th.
Workbook 1 Friday April 26th.
Solutions available here on Thursday May 2nd.
Solutions for Test 1a of Friday May 3rd. The remaining tests had the same questions in a different order: it is up to
you to work out the permutation!
Workbook 2 Friday May 3rd. Solutions available here on Thursday May 9th.
Solutions for Test 2a of Friday May 10th. The remaining tests had the same questions in a different order: it is up
to you to work out the permutation!

As mentioned during the test, Q1 should have 1 ≤ *r,s* ≤ 318, and Q2 should have *S*={1,3,7,15,31,...}. Also, in the solutions I handed
out, in A3 the required values of *n* are 1,2,3,4,6 (note the 6 instead of 5); the correct answer is still **(b)**.
Workbook 3 Friday May 10th.
Solutions available here on Thursday May 16th.
Solutions for Test 3a of Friday May 17th. The remaining tests had the same questions in a different order: it is up to
you to work out the permutation!
Workbook 4 Friday May 17th.
Solutions available here on Thursday May 23rd.
Solutions for Test 4a of Friday May 24th. The remaining tests had the same questions in a different order: it is up
to you to work out the permutation!
Workbook 5 Friday May 24th.
Solutions available here on Thursday May 30th. There is no test this Friday (May 31st).
