# Use sub-program

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.

**Input**

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**.

**Output**

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.

Input example

2 6 7.5 2.1 2.0

Output example

13.5000 45.0000 4.1000 4.2000

**Example description:**
Permission is granted to use 2 sub-program to find the sum and product respectively each separately.
