A rational number is one that can be expressed as a/b
The sum of two rational numbers is:
a/b + c/d
=ad/bd + bc/bd
=(ad+bc)/bd
=e/f
which is rational
The difference of two rational numbers is:
a/b - c/d
=ab/bd - bc/bd
=(ab-bc)/bd
=e/f
which is rational
The product of two rational numbers is:
(a/b)(c/d)
=ac/bd
=e/f
which is rational
The sum of any finite set of rational numbers is a rational number.
The sum or the difference between two irrational numbers could either be rational or irrational, however, it should be a real number.

Because both of those numbers are rational. The sum of any two rational numbers is rational.
The numbers are 13 and 8 The product is 104
Yes, it is.
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.
Yes. This is the same as asking for one rational number to be subtracted from another; to do this each rational number is made into an equivalent rational number so that the two rational numbers have the same denominator, and then the numerators are subtracted which gives a rational number which may possibly be simplified.
The sum of any finite set of rational numbers is a rational number.
The sum or the difference between two irrational numbers could either be rational or irrational, however, it should be a real number.
Such a sum is always rational.
When dealing with numbers greater than one, the sum will never be greater than the product. This question has no rational answer.

six, seven 7 + 6 = 13 (sum) 7 - 6 = 1 (difference) 7 x 6 = 42 (product)
six, nine 9 + 6 = 15 (sum) 9 - 6 = 3 (difference) 9 x 6 = 54 (product)
