Use this reverse calculator and give correct output

Its simple, In my Reverse calculator if you press 0 it will be considered as 9. Likewise 1 will be 8, 2 will be 7, 3 will be 6,......., 9 will be 0.

Here you will get two numbers and an operator(+ - * /). From this calculate the output.

Example:

 Inputs:
numbers=[3 4], operator='+'

 Output:
Value=11 (Because 3 will be considered as 6, 4 will be considered as 5. So 6+5=11)
