... Would this work if instead of 3, 5, 15 we had picked 3, 6, 18? What conditions must you put on two numbers m, n in order to have an operation preserving bijection: F : Z/mZ × Z/nZ → Z/(m · n)Z? Historical note: what you just showed (albeit in more modern language) is an ancient theorem called the Ch ...

... together, a = 1006 and b = 1005. Thus a 2  b 2  1006 2  1005 2 = 2022061. Method 2: Any odd number can be expressed as the difference between the squares of two consecutive integers. Therefore, (x + 1)2 – x2 = 2011. Thus, 2x + 1 = 2011 and x = 1005. Setting a = 1006 and b = 1005, a 2  b 2  1006 ...

Positional notation

Positional notation or place-value notation is a method of representing or encoding numbers. Positional notation is distinguished from other notations (such as Roman numerals) for its use of the same symbol for the different orders of magnitude (for example, the ""ones place"", ""tens place"", ""hundreds place""). This greatly simplified arithmetic leading to the rapid spread of the notation across the world.With the use of a radix point (decimal point in base-10), the notation can be extended to include fractions and the numeric expansions of real numbers. The Babylonian numeral system, base-60, was the first positional system developed, and is still used today to count time and angles. The Hindu–Arabic numeral system, base-10, is the most commonly used system in the world today for most calculations.
