Front
multiplying a number by a group of numbers added together is the same as doing each multiplication separately
Back
integers
Front
defined by the set -3, -2, -1, 0., 1, 2, 3, 4,...Contains both positive and negative whole numbers, this is an infinite set. Does not include fractions.
Back
complex number
Front
a number of the form a + bi where a and b are real numbers. Combination of real number and imaginary number.
Back
natural number
Front
counting numbers, defined by the set 1,2,3,4,... The three dots means that the pattern continues, this is an infinite set
