| x −0 | -0 |
Signed zero is zero with an associated sign. In ordinary arithmetic, −0 = 0. However, in computing, some number representations allow for the existence of two zeros, often denoted by −0 (negative zero) and +0 (positive zero). This occurs in some...

| x 201 |
201 is the natural number following 200 and preceding 202. It may be written as "two hundred one" or "two hundred and one".
As the two factors of 201 are both Gaussian primes, 201 is a Blum integer.
201 is a Harshad number in base 10.
