Subtraction Calculator

Quick answer

The subtraction calculator subtracts the subtrahend from the minuend and gives the difference, with an addition check.

Difference
637.25
Check: difference + subtrahend
1,000
Distance between the numbers
637.25

Subtraction finds how much is left or how far apart two numbers are. With negatives and decimals it is easy to slip a sign – the calculator does it reliably.

How to use the Subtraction Calculator

  1. Minuend
  2. Subtrahend

How it works

The difference is checked by adding it back to the subtrahend, which must give the minuend.

Inputs explained

Field What to enter
Minuend A number
Subtrahend A number

What each result means

  • Difference = [Minuend] – [Subtrahend]
  • Check: difference + subtrahend = ([Minuend] – [Subtrahend]) + [Subtrahend]
  • Distance between the numbers = abs([Minuend] – [Subtrahend])

Example values

How the main result changes when Minuend changes and everything else stays at the example values above:

Minuend Difference
500 137.25
750 387.25
1,000 637.25
1,250 887.25
1,500 1,137.25
2,000 1,637.25

Formula

Difference = minuend − subtrahend

Worked example

Inputs — Minuend: 1,000; Subtrahend: 362.75.
Results — Difference = 637.25; Check: difference + subtrahend = 1,000; Distance between the numbers = 637.25.

Key terms

Difference
The result of subtraction.

Frequently asked questions

What are the minuend and subtrahend?

In 10 − 3 = 7, 10 is the minuend, 3 the subtrahend and 7 the difference.

Is subtraction commutative?

No: 10 − 3 ≠ 3 − 10.

What is subtracting a negative?

Adding its opposite: 5 − (−2) = 7.

How do I check a subtraction?
