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.
Ratioal numbers
The number 15 belongs to an infinite amount of sets.
-12 belongs to at least the sets of all numbers, of integers and negative integers, of rational numbers and negative rational numbers, and all negative numbers.
-3
It belongs to infinitely many sets. Some notable sets to which it belongs include:* Integers * Negative integers * Rational numbers * Real numbers * Complex numbers
Negative integers, integers, negative rationals, rationals, negative reals, reals, complex numbers are some sets with specific names. There are lots more test without specific names to which -10 belongs.
-5
It is a whole number, integer, and a rational number. :D
the answer is -1
To any set that contains it! It belongs to {-3.15}, or {-3.15, sqrt(2), pi, -3/7}, or all numbers between -4 and +5, or negative numbers, or rational numbers, or real numbers, or complex numbers, etc.
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.
-28 belongs to: Integers, which is a subset of rationals, which is a subset of reals, which is a subset of complex numbers.
