FAQs
What is a cross sum?
A cross sum (also known as a digit sum) is the sum of all individual digits in a number. For example, the cross sum of 123 is 1 + 2 + 3 = 6.
Can I calculate cross sums for negative numbers?
Yes, our calculator handles negative numbers by calculating the cross sum of the absolute value. For example, -123 would be calculated as |1 + 2 + 3| = 6.
Is there a limit to the number size?
Our calculator can handle very large numbers, though for practical purposes we recommend numbers up to 100 digits. All calculations are performed instantly with detailed step-by-step breakdowns.
What are cross sums used for?
Cross sums are used in mathematics for various purposes, including digital root calculations, number theory, and as a quick check for divisibility. They're also used in some forms of numerology and mathematical puzzles.
