The problem gives you two integers, a and b, on separate lines. You need to print three values, each on its own line: a + b (sum)
a - b (difference)
a * b (product) The input format is simple: two lines, each containing one integer. The output format is also simple: three lines, each containing one result. No tricky edge cases here. If a = 3 and b = 2, you print , then , then .
