Read the whole line as a string and split it to two terms by the equality operator.
Then parse each number and each operator, calculate both sides of the equation and compare the results.

This task is not that easy. If you're unexperienced I'd recommend to focus on a simple equation first, e.g. only one side and only one operator and proceed step by step once this solution works.
