-10 belongs to the set of all integers denoted by Z.
17 belongs to the set of prime numbers
belongs to an infinite number of sets. For example, the Real Numbers, the Rational Numbers, Integers, negative integers, odd negative integers, negative primes numbers, the set {12, -17, 98} or {2.76, pi, -17, k, wikianswers}. In fact any collection, however random, of numbers or other things, that includes -17.
The number 15 belongs to an infinite amount of sets.
Ratioal numbers
the answer is -1
-3
173 belongs to the set of positive natural numbers and it also belongs to the set of prime numbers.
Of the "standard sets" -10 belongs to: ℤ⁻ (the negative integers) ℤ (the integers) ℚ⁻ (the negative rational numbers) ℚ (the rational numbers) ℝ⁻ (the negative real numbers) ℝ (the real numbers) ℂ (the complex numbers) (as ℤ ⊂ ℚ ⊂ ℝ ⊂ ℂ). Other sets are possible, eg the even numbers.
Pi belongs to the sets of real numbers, transcendental numbers and irrational numbers.
It belongs to infinitely many sets. Some notable sets to which it belongs include:* Integers * Negative integers * Rational numbers * Real numbers * Complex numbers
