Common Formulas

Percentages

X% of Y = Y × X ÷ 100
Y + X% = Y × (1 + X/100)
Y − X% = Y × (1 − X/100)

Compound Interest

A = P(1 + r/n)^(nt)

Loan Payment

PMT = PV × [r(1+r)ⁿ] / [(1+r)ⁿ − 1]

Distance-Rate-Time

Distance = Rate × Time

Quadratic Formula

x = (−b ± √(b²−4ac)) / 2a

Quick Conversions

Temperature

• °F = °C × 9/5 + 32
• °C = (°F − 32) × 5/9

Length

• 1 inch = 2.54 cm
• 1 mile = 1.609 km
• 1 foot = 0.3048 m

Tips for Success

1. Use 2ndF for inverse functions
2. Use Memory for multi-step calculations
3. Check angle mode before trig functions
4. Use EE for scientific notation
5. Compare regression r² for best fit
