In modular arithmetic, two integers are added and then the sum is divided by a positive integer called the modulus. The result of modular addition is the remainder of that division. For any modulus, n, the set of integers from 0 to n 1 forms a group under modular addition: the inverse of any element a is n a, and 0 is the identity element. This is familiar from the addition of hours on the face of a clock: if the hour hand is on 9 and is advanced 4 hours, it ends up on 1, as shown at the right. This is expressed by saying that 9 + 4 equals 1 "modulo 12" or, in symbols,
What type of device can be use to demonstrate modular addition?
****
The answer: a clock

In the years to follow, public revelations on the state of Charles and Diana's marriage continued. Even though support for republicanism in Britain seemed higher than at any time in living memory, republicanism was still a minority viewpoint, and the Queen herself had high approval ratings. Criticism was focused on the institution of the monarchy itself and the Queen's wider family rather than her own behaviour and actions. In consultation with her husband and the Prime Minister, John Major, as well as the Archbishop of Canterbury, George Carey, and her private secretary, Robert Fellowes, she wrote to Charles and Diana at the end of December 1995, saying that a divorce was desirable.
When did Elizabeth write to tell Charles and Diana to get a divorce?
****
The answer: December 1995

The Middle Triassic spans from 247 million to 237 million years ago. The Middle Triassic featured the beginnings of the breakup of Pangaea, and the beginning of the Tethys Sea. The ecosystem had recovered from the devastation that was the Great Dying. Phytoplankton, coral, and crustaceans all had recovered, and the reptiles began to get bigger and bigger. New aquatic reptiles evolved such as Ichthyosaurs and Nothosaurs. Meanwhile, on land, Pine forests flourished, bringing along mosquitoes and fruit flies. The first ancient crocodilians evolved, which sparked competition with the large amphibians that had since ruled the freshwater world.
What is the span of years of the Middle Triassic?
****
The answer: 247 million to 237 million
