@luke_parham, I have put down the code exactly as you showed but when trying to sh script.sh I see a message:
This is interpolation A = 10

This is not B != $B

script.sh: line 10: syntax error in conditional expression

script.sh: line 11: syntax error near `then’

script.sh: line 11: `then’

Please explain what might be wrong?
