Lander, Parkin, and Selfridge conjecture: if the sum of -th powers of positive integers is equal to a different sum of -th powers of positive integers, then +. Lemoine's conjecture : all odd integers greater than 5 {\displaystyle 5} can be represented as the sum of an odd prime number and an even semiprime .
When 2 5 is entered, it is picked up by the scanning unit; the number 25 is encoded and sent to the X register; Next, when the + key is pressed, the "addition" instruction is also encoded and sent to the flag or the status register; The second number 9 is encoded and sent to the X register. This "pushes" (shifts) the first number out into the Y ...
A game of Snatch in progress. Anagrams (also called Snatch or Snatch-words) is a fast-paced, non-turn-based Scrabble variant played without a board. The tiles are placed face-down in the middle of the table, and players take turns flipping a single tile, leaving it in clear view of all players.
For larger scales the sum of the angles of a triangle is not equal to 180°. Geometry is one of the oldest branches of mathematics. It started with empirical recipes concerning shapes, such as lines , angles and circles , which were developed mainly for the needs of surveying and architecture , but has since blossomed out into many other subfields.
1 Bq = 1 s −1. A special name was introduced for the reciprocal second (s −1) to represent radioactivity to avoid potentially dangerous mistakes with prefixes.For example, 1 μs −1 would mean 10 6 disintegrations per second: (10 −6 s) −1 = 10 6 s −1, [4] whereas 1 μBq would mean 1 disintegration per 1 million seconds.
By performing the calculation above in the familiar decimal system, we see why 112 in octal is equal to + + = in decimal. Octal numerals can be easily converted from binary representations (similar to a quaternary numeral system ) by grouping consecutive binary digits into groups of three (starting from the right, for integers).
Diophantus was born into a Greek family and is known to have lived in Alexandria, Egypt, during the Roman era, between AD 200 and 214 to 284 or 298. [6] [8] [9] [a] Much of our knowledge of the life of Diophantus is derived from a 5th-century Greek anthology of number games and puzzles created by Metrodorus.
Hexadecimal (also known as base-16 or simply hex) is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen.
