Common Challenges & Solutions
Every beginner faces obstacles. Here's how to overcome them:
⚠️
Mental math is too hard
Solution: Start with estimation and rounding. Don't worry about exact answers - being close is the skill. Write down your work if needed. Speed comes with practice.
⚠️
Don't understand percentages
Solution: Percentage means 'out of 100.' To find X% of something: X ÷ 100 × amount. Example: 20% of $50 = 20÷100×50 = 0.20×50 = $10. Practice with simple numbers first.
