The sum of any finite set of rational numbers is a rational number.
Because both of those numbers are rational. The sum of any two rational numbers is rational.

The sign of the sum is positive when the absolute value of the positive addend is greater than that of the negative addend.
No
Yes.
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.
Such a sum is always rational.
Because both of those numbers are rational. The sum of any two rational numbers is rational.
No - the sum of any two rational numbers is still rational:
Since the sum of two rational numbers is rational, the answer will be the same as for the sum of an irrational and a single rational number. It is always irrational.
They are always rational.
Yes, it is.
Yes, it is.
Yes, Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Yes.
It is a rational number.
Every time. The sum of two rational numbers MUST be a rational number.
