According to a legend the Chinese emperor yu Huang saw a magic square on the back of a turtle. In a magic square on the back of a turtle. In a magic square, the numbers in each column gave the same sum. This sum is called the magic sum. Copy and complete the magic square so that each row and each column has a magic sum of 0. Use each integer from -4 to 4 exactly once

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?
