Harry and terry are each told to calculate 8−(2+5)8−(2+5). harry gets the correct answer. terry ignores the parentheses and calculates 8−2+58−2+5. if harry's answer is hh and terry's answer is tt, what is h−th−t?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
