Count the number of negative numbers. If this is an even number, the sign is + and if it is odd, the sign is -.
Multiply them together.
Count the number of negative values. If that number is even, the answer is positive and if it is odd, the answer is negative.
The sum of two rational numbers is rational.From there, it follows that the sum of a finite set of rational numbers is also rational.
No. The set of real numbers contains an infinitely more irrational numbers than rational numbers.
They make a rational number.
Multiply them together.
Count the number of negative values. If that number is even, the answer is positive and if it is odd, the answer is negative.
Two or more numbers are needed to find their product

There are more irrational numbers between any two rational numbers than there are rational numbers in total.
Two or more numbers are needed to find their product in multiplication.
Two or more numbers are normally needed to find the product
Infinitely many. In fact, there are more irrational numbers between them than there are rational numbers.Infinitely many.

Every odd or even number is a rational number, and there are a lot more rational numbers besides those.
Both are part of the real numbers; both are infinite sets. (However, there are more irrational than rational numbers.)Both are part of the real numbers; both are infinite sets.

No. In fact, there are infinitely more irrational numbers than there are rational numbers.
The short answer to your question: yes. This is one of the central axioms of math. If you'd like a bit more detail, try researching number theory.
