Subtraction of Small Numbers Calculator

Published on: January 7, 2024

This Subtraction of Small Numbers Calculator helps you subtract simple integers and shows each step clearly on a number line. Start at the first number, then move left when subtracting a positive number and right when subtracting a negative number. Continue from each new position until all numbers have been subtracted. It is a simple way to check answers, understand subtraction visually, and practise basic arithmetic step by step.

Step-by-step method

  1. Start at the first number on the number line.
  2. Subtract the next number (a positive number). Move left that many steps.
  3. If there are more numbers, start where you land and repeat.

Example 1: 7 − 5

Step 1 - Start at the first number on the number line.

In this problem: Start at 7.

Example 1 — Step 1: Start at 7

Step 2 - Subtract the next number (a positive number). Move left that many steps.

In this problem: Subtract 5 → move left 5 steps → land on 2.

Example 1 — Step 2: Subtract 5 (7 → 2)

Final answer: 7 − 5 = 2

Example 2: 14 − 6 − 3

Step 1 - Start at the first number on the number line.

In this problem: Start at 14.

Example 2 — Step 1: Start at 14

Step 2 - Subtract the next number (a positive number). Move left that many steps. If there are more numbers, start where you land and repeat.

In this problem: Subtract 6 → move left 6 steps → land on 8.

Example 2 — Step 2: Subtract 6 (14 → 8)

Step 3 - Subtract the next number (a positive number). Move left that many steps.

In this problem: Now start at 8. Subtract 3 → move left 3 steps → land on 5.

Example 2 — Step 3: Subtract 3 (8 → 5)

Final answer: 14 − 6 − 3 = 5

Tip: Subtracting a negative number is the same as addition. Example: 8 − (−3) is the same as 8 + 3 (that would be 3 steps right).
