A number is an abstract concept used for counting or measuring. There are many kinds of numbers: [[prime numbers]], [[composite numbers]], [[real numbers]], [[complex numbers]]. Some people believe certain numbers are lucky, or unlucky, such as [[13]]. These beliefs and belief in [[numerology]] is generally not considered compatible with [[Christian]] beliefs. | A number is an abstract concept used for counting or measuring.
