A proof consists of a succession of applications of deductive rules to already established results. These objects consist of either abstractions from nature or-in modern mathematics-entities that are stipulated to have certain properties, called axioms. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. There is no general consensus among mathematicians about a common definition for their academic discipline. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. When a number touches the same number of squares, those squares must be mines.Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes.

You also can play Custom games up to 30x24 with a minimum of 10 mines and maximum of (x-1)(y-1) mines. Minesweeper saves your best time for each difficulty level. A counter shows the number of mines without flags, and a clock shows your time in seconds. The game ends when all safe squares have been opened. The three difficulty levels are Beginner (8x8 or 9x9 with 10 mines), Intermediate (16x16 with 40 mines) and Expert (30x16 with 99 mines). This can save you a lot of work! However, if you place the correct number of flags on the wrong squares, chording will explode the mines. Chording is when you press both mouse buttons at the same time. If you flag all of the mines touching a number, chording on the number opens the remaining squares. A common strategy for starting games is to randomly click until you get a big opening with lots of numbers. When you open a square that does not touch any mines, it will be empty and the adjacent squares will automatically open in all directions until reaching squares that contain numbers. Pressing the right mouse button again changes your flag into a questionmark. You open squares with the left mouse button and put flags on mines with the right mouse button.

Windows Minesweeper always makes the first click safe. If you click on a mine you lose the game! You can use the number clues to solve the game by opening all of the safe squares. Safe squares have numbers telling you how many mines touch the square. Minesweeper is a game where mines are hidden in a grid of squares. Minesweeper on Windows XP with 40 mines solved in 28 seconds
