What should I learn before starting finance if I have never followed financial markets?

Before starting finance, build a foundation in basic algebra, percentages, ratios, graphs, and introductory statistics. Learn the essentials of economics, accounting, interest and inflation, and how financial markets, shares, bonds, funds, and risk work. Practise reading financial statements and using spreadsheets, while developing the habit of checking reliable financial information rather than relying on predictions or social media.
