Part and whole

Vyastisamastih

This sutra uses the 'part and whole' strategy to simplify calculations involving groups of numbers. By choosing a convenient base (the assumed average), you work with small deviations instead of large numbers, making mental math much easier.

How It Works

1.Choose a convenient base value close to all numbers in the set.
2.Calculate the deviation of each number from the base.
3.Sum all the deviations — positive and negative will often cancel out.
4.Average = base + (sum of deviations ÷ count).
5.This avoids adding large numbers together.

Examples

Average of 41, 43, 47, 49

Step 1 / 4

Find the average of: 41, 43, 47, 49. Pick a round number near the middle as the base.
