Calculate the sum and product N pairs which set material numbers, having taken advantage of subroutine SumDob for calculation of the sum and product of two material numbers.
In the first line set the natural number N - quantity of pairs numbers. In the subsequent N lines through a blank it set on 2 material numbers. All input on the module does not exceed 100.
In N lines deduce through a blank on two numbers: at first the sum, and then product of the next pair numbers. Result deduces with accuracy 4 signs after a decimal point.
