Puranapuranabhyam: Completion & Compensation

Puranapuranabhyam uses completion or non-completion to make a calculation friendlier. Move a number towards a convenient total, calculate, then compensate for the adjustment.

Use friendly numbers for mental calculation

For 998 + 467, temporarily complete 998 to 1,000, add 467 and subtract the extra 2. The same idea can help with subtraction and other convenient number adjustments.
