... Solution: First we choose 3 places for even digits. This can be done in 63 = 20 ways. Observe that the other places for odd digits get automatically fixed. There are 5 even digits and 5 odd digits. Any of these can occur in their proper places. Hence there are 56 ways of selecting 3 even and 3 odd d ...

... every step. But the initial three numbers are not all the same. Hence the final difference between the smallest and largest of the three numbers is 1 and the largest number on the board is 501. A second proof. By going backwards (a, b, c) 7→ (a + b − c, a − b + c, −a + b + c) we see that if the fina ...

Complex Numbers
... A complex number is a number of the form x + iy where x and y are real numbers and i is the imaginary unit. The imaginary unit i is the complex number with the property i2 = −1. For example 1 + 2i and 2 − 3i are complex numbers. The notations x + iy and x + yi are used interchangeably. All real numb ...

Infinity
Infinity (symbol: ∞) is an abstract concept describing something without any limit and is relevant in a number of fields, predominantly mathematics and physics.In mathematics, ""infinity"" is often treated as if it were a number (i.e., it counts or measures things: ""an infinite number of terms"") but it is not the same sort of number as natural or real numbers. In number systems incorporating infinitesimals, the reciprocal of an infinitesimal is an infinite number, i.e., a number greater than any real number; see 1/∞.Georg Cantor formalized many ideas related to infinity and infinite sets during the late 19th and early 20th centuries. In the theory he developed, there are infinite sets of different sizes (called cardinalities). For example, the set of integers is countably infinite, while the infinite set of real numbers is uncountable.
