You are watching: Name the set(s) of numbers to which –10 belongs.
Integers
The whole numbers, 1,2,3,... An unfavorable whole number ..., -3,-2,-1 and zero 0. For this reason the collection is ..., -3, -2, -1, 0, 1, 2, 3, ...

Rational Numbers
The numbers you have the right to make by splitting one creature by an additional (but not separating by zero). In other words fractions. Read an ext ->
Q is for "quotient" (because R is supplied for the set of genuine numbers).
Examples: 3/2 (=1.5), 8/4 (=2), 136/100 (=1.36), -1/1000 (=-0.001)
(Q is from the Italian "Quoziente" definition Quotient, the an outcome of separating one number through another.)
Irrational Numbers
Any real number that is not a rational Number. Read more ->

Algebraic Numbers
Any number that is a equipment to a polynomial equation v rational coefficients.
Includes every Rational Numbers, and also some Irrational Numbers. Read an ext ->
Transcendental Numbers

Real Numbers

They are dubbed "Real" numbers due to the fact that they are not imaginary Numbers. Read much more ->

Imaginary Numbers
Numbers that as soon as squared give a an adverse result.
If you square a real number you always get a positive, or zero, result. For example 2×2=4, and also (-2)×(-2)=4 also, so "imaginary" numbers deserve to seem impossible, but they room still useful!
Examples: √(-9) (=3i), 6i, -5.2i
The "unit" imaginary number is √(-1) (the square root of minus one), and its price is i, or occasionally j.
i2 = -1

Complex Numbers
A mix of a real and an imaginary number in the type a + bi, whereby a and b space real, and also i is imaginary.
The values a and b deserve to be zero, for this reason the collection of genuine numbers and also the collection of imaginary numbers space subsets the the set of facility numbers.
Examples: 1 + i, 2 - 6i, -5.2i, 4

Number to adjust In Use
Here room some algebraic equations, and also the number collection needed to settle them:
x − 3 = 0 | x = 3 | Natural number | |
x + 7 = 0 | x = −7 | Integers | |
4x − 1 = 0 | x = ¼ | Rational number | |
x2 − 2 = 0 | x = ±√2 | Real Numbers | |
x2 + 1 = 0 | x = ±√(−1) | Complex Numbers |

We have the right to take an existing collection symbol and place in the height right corner:
