Questions series of mathematical operation

An input-output is given in different steps. Some mathematical operations are done in each step. No mathematical operation is repeated in next step but it can be repeated with some other mathematical operation (as multiplication can be used with subtraction in step 1 and same can be used with addition in step 2) As per the rules followed in the steps given above, find out in each of the following questions the appropriate step for the givne input What is the result of addition of numbers obtained in step 3?
