Use the programming interface to complete this task. You'll be given a math expression, such as add 1 2 or subtract 5 3, where you will perform the operations 1+2 and 5-3, respectively.
ID: math-class
Input: An expression in the form of operation operand1 operand2, separated by spaces. Read input from math-class.in.
Output: The absolute value of the evaluated expression. Your output should always be a positive integer.
There are only 2 different possible operations, addition and subtraction, and all operands will be integer values between 1 and 1000. As always, remember to end your program with a newline.
Two very useful functions are int() and split(). Read about them in the documentation.
