Multiplying 2-Digit by 2-Digit
Example: 23 × 14. Step 1: 23×4 = 92. Step 2: 23×10 = 230 (multiply by tens digit, add zero). Step 3: Add: 92+230 = 322. Written method: write partial products separately, then add. Grid method: draw 4 boxes, multiply each part. 20×10=200, 20×4=80, 3×10=30, 3×4=12. Add all: 200+80+30+12=322. All methods give same answer!
