Distraction from work is a common problem.

The best thing to do is to work somewhere with as few distractions are possible. Just you, a chair, a table and your work. No computers, pictures, phones, or anything else.

Make yourself as comfortable as possible (go to the toilet, have a drink, etc). Then it's just a case of self-discipline. Only you can force yourself to engage and do the work. It's something we all have to learn in life.

To make things even easier, set yourself reasonable targets. Tell yourself that once you've done 5 math questions, you will have a break. Then it won't seem such a huge task and you might be able to get on with it.
