a.) The answer to the sum of any rational number will always equal a rational number since no irrational forms will appear
Ex.) + = [ is the same as 1]
Fractions and whole numbers are rational numbers and the answer still equals a fraction.
b.) The sum of 2+ irrational numbers is still irrational numbers.
Ex.) + = 2 We are only adding the two irrational stars so there is still a square root in the sum making it irrational.
