32 (number)
32 (thirty-two) is the fifth power of two, a number that shapes computing through 32-bit processors and IEEE single-precision floats, and equals the atomic number of germanium.
Cube (algebra)
The cube of a number, or cubic number, is the number multiplied by itself twice, written a3; cubing gives the volume of a cube with edge a.
Perfect power
A perfect power is a positive integer that can be written as m^k, with m > 1 and k at least 2, such as 4, 8, 9, and 27.
Power of 10
A power of 10 is a number like 100 or 1000, written 10 to the nth power, that underlies decimal notation and the SI metric prefixes.
Power of two
A power of two is a number written as 2 to a whole-number exponent, beginning 1, 2, 4, 8, 16, 32, and important in computing.
Square number
A square number, or perfect square, is an integer that is the product of an integer with itself, such as 0, 1, 4, 9, 16, and 25.
Wheat and chessboard problem
