Enter your minuend (first number) and subtrahend (second number) to calculate the difference. The Subtraction Calculator returns the result along with a step-by-step borrowing (regrouping) breakdown — showing exactly how each place value column is handled from ones through thousands.

A subtraction calculator is an online tool that computes the difference between two numbers. This version also shows the long subtraction process with regrouping (borrowing) steps, making it useful for learning or verifying manual calculations.
Simply enter the first number (minuend) in the top field and the second number (subtrahend) in the bottom field, then press Calculate. The calculator instantly shows the difference and a column-by-column borrowing breakdown.
Regrouping, also called borrowing, happens when the digit being subtracted in a column is larger than the digit above it. You borrow 1 from the next column to the left, adding 10 to the current column so the subtraction can proceed.
Yes. You can enter decimal numbers in either field. The calculator aligns decimal points correctly and performs long subtraction across all place values, including tenths and hundredths.
If the subtrahend is larger than the minuend, the result will be a negative number. The calculator handles this correctly and displays the negative difference.
Place values refer to the positional value of each digit — ones, tens, hundreds, thousands, and so on. In long subtraction, you work column by column from right (ones) to left, borrowing from higher-value columns when needed.
The number of steps equals the number of digit columns in the larger number. Each column is processed individually, and any column requiring borrowing adds one extra sub-step. This calculator shows every step in the table below the result.
The final answer is identical to pressing minus on any calculator. The difference here is that this tool also shows the manual long subtraction method with regrouping steps, which is especially helpful for students learning arithmetic.
