Base Method Multiplication

Step 1: Identify the nearest base (10, 100, 1000, 10000) - always a power of 10.
Step 2: Find the deficiency for each number = Base − Number (write as negative if below base).
Step 3: Calculate the Left Hand Side (LHS) by cross-subtraction: Number₁ − Deficiency₂.
Step 4: Calculate the Right Hand Side (RHS) = Deficiency₁ × Deficiency₂ (absolute values).
Step 5: Ensure RHS has the same number of digits as zeros in the base (add leading zeros if needed).
Step 6: Combine LHS and RHS to get the final product.

568 × 998

Base: 1000 | Deficiency Method

FINAL ANSWER

566,864

💡 Random Practice Challenge: Try 487 × 996 using the same method!
