... line x = y, the result is a lattice path from (0, 0) to (n, n) that never goes above the diagonal. One can also think of such a path as a path from (1, 0) to (n + 1, n) that never touches or crosses the diagonal. As the article on ballot numbers explains, these paths are counted by the Catalan numbe ...

... Now, let us try and look at natural numbers from the other direction. Let us take any collection of prime numbers, say 2, 3, 7, 11 and 23. If we multiply some or all of these numbers, allowing them to repeat as many times as we wish, we can produce infinitely many large positive integers. Let us lis ...

... We measure speeds in kilometres per hour so if it does 5 km in 15 minutes you would expect it to travel 10 km in 30 minutes and 20 km in 60 mins. The speed is therefore 20 km per hour Answer 20 km per hour b) A car travels 9 miles in 12 minutes, what is its average speed? We measure speeds in miles ...
