Increase All Digits in a Number

Counting can be done backwards: instead of adding to the value, add to the characters. Each digit climbs on its own - a 4 becomes 5, a 9 becomes 10 - and because no column ever carries, a number like 199 grows into something no ordinary addition would ever produce: 2,10,10. It is less arithmetic, more a puzzle game played on the digits themselves.

Increase All Digits in a Number adds the same amount to every digit in the value, column by independent column. Choose how much to add, and the tool rewrites each digit in place - signs stay up front and the decimal point holds its position. See the per-column breakdown and copy or download the result.

• No carrying: Every digit is increased independently, column by column.
• Per-digit amount: Add from 1 to 9 to each digit.
• Column breakdown: The result shows each original and increased digit side by side.
• Sign-safe: A leading plus or minus never gets increased.
• Decimal aware: Only integer digits change; the point stays put.
• Text-exact: Every column computes exactly at any number size.
• Copy or download: Export the transformed number for puzzles or patterns.
• Free and private: Everything runs locally; nothing is uploaded or stored.

1. Enter a number - with any sign or decimal part you need kept.
2. Choose the amount - how much each digit should climb, 1 to 9.
3. Read the per-column result - every digit increased in place.
4. Check the breakdown - original and increased digits side by side.
5. Copy or download the transformed number.

Example 1 - All climb. Enter 1234, add 1: 2,3,4,5.

Example 2 - The carryless nine. Enter 199, add 1: 2,10,10 - no carrying, each column alone.

Example 3 - Higher amount. Enter 568, add 2: 7,8,10.

Example 4 - Sign kept. Enter -123, add 1: -2,3,4 - the sign never increases.

Example 5 - Decimal. Enter 4.9, add 1: 5.10 - the point stays, the fraction digit climbs too.
