If a subsequent number is two digits, for example, 18, you will add the two digits together — for this situation, get 9. Include these numbers.
Then include the digits you skipped when you were doing the multiplying. At last, add those aggregates together, and take a look at the digit. The outcome will be distinguishable by 10.5
