Numbers 6, 7, 8, 9 are called butterfly numbers.

Which numbers are called butterfly numbers?

In ones = 6, 7, 8, 9

In tens  60, 70, 80, 90

In hundreds = 600, 700, 800, 900

In thousands = 6000, 7000, 8000, 9000

and so on.

Why these numbers are called butterfly numbers?

Because, while doing addition and subtraction of the numbers 6, 7, 8, and 9 with the help of the abacus we use the index and thumb fingers like a butterfly.
