In a certain sense, the set of complex numbers is "larger" than the set of real numbers, since the set of real numbers is a proper subset of it.
The complement of a set refers to everything that is NOT in the set. A "universe" (a set from which elements may be taken) must always be specified (perhaps implicitly). For example, if your "universe" is the real numbers, and the set you are considering is 0
The set of natural numbers less than four is {1, 2, 3}.
The set of prime numbers less than 20 = {2, 3, 5, 7, 11, 13, 17,19}

the set of whole numbers less than 0
Real numbers are all numbers. So the answer would be -4 and every number after that in the negative direction. So any number that is less than -4. So, -5, -6, and so on.
Thin of the number line with a solid dot on the number -4. Everything to the left of your dot satisfies real numbers less than or equal to 4. The set it infinite, of course. In set builder notation, {x: x< or = 4}
The set of all real numbers less than or equal to -6 can be represented as (-∞, -6]. This notation indicates that the set includes all real numbers from negative infinity up to and including -6. In interval notation, the square bracket [ denotes that -6 is included in the set, while the parentheses ( indicate that negative infinity is not a specific value in the set.

The set of natural numbers less than four is {1, 2, 3}.
Set of even numbers less than 50 and more than 40 = {42,44,46,48}
The LCM of two numbers will never be less than the GCF.
The answer to this is 2, and 0.
