Addition of Small Numbers Calculator

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

Step-by-step method

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

An Empty Number Line (-5 to 5)

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 - Add the next number (a positive number). Move right that many steps.

In this problem: Add 5 → move right 5 steps → land on 12.

Example 1 — Step 2: Add 5 (7 → 12)

Final answer: 7 + 5 = 12

Example 2: 4 + 7 + 3

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

In this problem: Start at 4.

Example 2 — Step 1: Start at 4

Step 2 - Add the next number and move right that many steps. If there are more numbers, start where you land and repeat.

In this problem: Add 7 → move right 7 steps → land on 11.

Example 2 — Step 2: Add 7 (4 → 11)

Step 3 - Add the next number and move right that many steps.

In this problem: Now start at 11. Add 3 → move right 3 steps → land on 14.

Example 2 — Step 3: Add 3 (11 → 14)

Final answer: 4 + 7 + 3 = 14

Tip: Adding a negative number is the same as subtraction. Example: 8 + (−3) is the same as 8 − 3 (that would be 3 steps left).
