# Adding and Subtracting Integers Calculator

## Calculator Use

Add and subtract positive and negative whole numbers or real numbers. Use numbers, + and -. You can also include expressions within parentheses and the calculator will solve the full equation.

For more complex math equations that require order of operations or PEMDAS, use the Math Equation Solver.

## Adding and Subtracting Positive and Negative Numbers

This Adding and Subtracting Integers Calculator evaluates equations with positive and/or negative numbers using addition and/or subtraction. The calculator uses standard mathematical rules to solve the equations.

### Rules for Addition Problems

If signs are the same then keep the sign and add the numbers.

If signs are different then subtract the smaller number from the larger number and keep the sign of the larger number.

### Rules for Subtraction Problems

Keep the sign of the first number. Change the subtraction operations to addition operations. Change the sign of the numbers that follow to the opposite, i.e., positive becomes negative, and negative becomes positive. Then follow the rules for addition problems.
