Common Number Sets
There are sets of numbers that are used so often they have special names and symbols:
The whole numbers from 1 upwards. (Or from 0 upwards in some fields of mathematics). Read More ->
The whole numbers, <1,2,3. >negative whole numbers <. -3,-2,-1>and zero <0>. So the set is
(Z is from the German “Zahlen” meaning numbers, because I is used for the set of imaginary numbers). Read More ->
The numbers you can make by dividing one integer by another (but not dividing by zero). In other words fractions. Read More ->
Q is for “quotient” (because R is used for the set of real numbers).
Examples: 3/2 (=1.5), 8/4 (=2), 136/100 (=1.36), -1/1000 (=-0.001)
(Q is from the Italian “Quoziente” meaning Quotient, the result of dividing one number by another.)
Any real number that is not a Rational Number. Read More ->
Any number that is a solution to a polynomial equation with rational coefficients.
Includes all Rational Numbers, and some Irrational Numbers. Read More ->
Any number that is not an Algebraic Number
Examples of transcendental numbers include π and e. Read More ->
All Rational and Irrational numbers. They can also be positive, negative or zero.
Includes the Algebraic Numbers and Transcendental Numbers.
A simple way to think about the Real Numbers is: any point anywhere on the number line (not just the whole numbers).
Examples: 1.5, -12.3, 99, √2, π
They are called “Real” numbers because they are not Imaginary Numbers. Read More ->
Numbers that when squared give a negative result.
If you square a real number you always get a positive, or zero, result. For example 2×2=4, and (-2)×(-2)=4 also, so “imaginary” numbers can seem impossible, but they are still useful!
Examples: √(-9) (=3i), 6i, -5.2i
The “unit” imaginary numbers is √(-1) (the square root of minus one), and its symbol is i, or sometimes j.
A combination of a real and an imaginary number in the form a + bi, where a and b are real, and i is imaginary.
The values a and b can be zero, so the set of real numbers and the set of imaginary numbers are subsets of the set of complex numbers.
Examples: 1 + i, 2 – 6i, -5.2i, 4
Natural numbers are a subset of Integers
Integers are a subset of Rational Numbers
Rational Numbers are a subset of the Real Numbers
Combinations of Real and Imaginary numbers make up the Complex Numbers.
Number Sets In Use
Here are some algebraic equations, and the number set needed to solve them:
|x − 3 = 0||x = 3||Natural Numbers|
|x + 7 = 0||x = −7||Integers|
|4x − 1 = 0||x = ¼||Rational Numbers|
|x 2 − 2 = 0||x = ±√2||Real Numbers|
|x 2 + 1 = 0||x = ±√(−1)||Complex Numbers|
We can take an existing set symbol and place in the top right corner:Common Number Sets There are sets of numbers that are used so often they have special names and symbols: The whole numbers from 1 upwards. (Or from 0 upwards in some fields of mathematics).
