Answer :

This question is based on modal verbs.

Cambridge English Dictionary defines 'modal verb' as 'a verb used with another verb to express an idea such as possibility that is not expressed by the main verb.'

The given sentence 'You should compulsory work on mathematics so that you HAVE THE ABILITY to work out the problem.' can be rewritten by using appropriate modal auxiliary in place of capital words in the following manner :

You should compulsory work on mathematics so that you can work out the problem.

Here, the modal auxiliary 'can' denotes someone's ability to do something.

Cambridge English Dictionary defines 'can' as 'to be able to.'
