Adding and Subtracting Integers Calculator

What is the Adding and Subtracting Integers Calculator?

The Adding and Subtracting Integers Calculator is a free online tool that helps you solve integer addition and subtraction problems. It handles positive and negative whole numbers, supports parentheses for grouping, and shows step-by-step work so you can see how the result is derived.

Integers are whole numbers that can be positive, negative, or zero. This calculator focuses on addition and subtraction of integers, making it perfect for students learning about negative numbers, teachers preparing lessons, or anyone who needs to quickly compute integer expressions.

How to Use the Integer Calculator

Simply type your integer expression into the input field using numbers, the plus sign (+), the minus sign (-), and parentheses ( ) for grouping. The calculator will automatically evaluate the expression using standard order of operations (PEMDAS) and show you each step of the calculation.

Rules for Adding and Subtracting Integers

When adding integers, if the signs are the same, keep the sign and add the numbers. If the signs are different, subtract the smaller number from the larger number and keep the sign of the larger number. For subtraction, keep the sign of the first number, change subtraction to addition, and change the sign of the following number, then follow the addition rules.
