How to study mathematics

Maths is learned by doing problems, and nothing replaces that. What notes and questions can do is make sure you understand the definitions, theorems and methods before you start, so the problems teach you something instead of just stopping you.

IS lecture – week 4

29/08/2026, Audio, 48 min

Quick overview

Business information systems collect and process the information that supports decision-making in companies.

Key takeaway: Without good data, even the best system will not produce good decisions.

Types of system

  • Transactional – captures the day-to-day business events.
  • Decision support – analysis and scenarios for management.
  • ERP – ties the processes into one data model.

Why it is hard to learn

A study plan that works

  1. Get the theory straight

    Upload the lecture or the chapter. Memo's notes write formulas out properly and explain what each definition and theorem says.

  2. Learn the definitions and theorems

    Put each one on a flashcard: the statement on one side, when to use it on the other.

  3. Ask about the steps you do not follow

    When a worked example skips a step, ask the chat on the note to explain it.

  4. Then practise problems

    Work through your problem sets and past papers. That part is yours, and it is the part the exam grades.

The study modes that fit best

Notes

For definitions, theorems and methods, written out clearly.

Flashcards

For the exact statements you have to know.

Quiz

To check you know which method fits which problem.

Mind map

To see how a chapter's ideas build on each other.

Questions

Can Memo solve my maths problems?

It can explain a step you are stuck on. But solving problems yourself is the practice that makes you good at maths, and it is what the exam grades.

Does Memo show formulas properly?

Yes. Formulas and equations in the notes are written out as maths, not as plain text.
