Common Myths
❌ "I'm just not a math person". Math is a skill, not a talent.
❌ "I'll never use this in real life". These skills directly impact your wealth.
❌ "Calculators make math unnecessary". Understanding concepts prevents costly errors.
❌ "Business math is too complex". Most business math is just careful arithmetic.
Recommended Tools
- Calculator: Your smartphone or a scientific calculator
- Spreadsheet: Google Sheets (free) or Microsoft Excel
- Practice: Khan Academy (free math practice)
- Finance: YNAB, Mint, or similar for tracking real numbers
