Use this calculator for adding and subtracting integers. Positive and negative whole numbers are integers. The calculator shows the work for the math and shows you when to change the sign for subtracting negative numbers.

Add and subtract positive and negative integers, whole numbers, or decimal numbers. Use numbers + and -. You can also include numbers with addition and subtraction in parentheses and the calculator will solve the equation.

Input Examples ? Inputs Answer No parentheses -10 - -22 + 33 45 With parentheses (-10) - (-22) + 33 45 Equation -10 - (-22 + 33) -21 Adding and Subtracting Positive and Negative Numbers

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

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

Rules for Adding Integers

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

(-) + (-) = (-) (+) + (+) = (+) -21 + -9 = - 30 (+7) + (+13) = (+20)

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

(-Large) + (+Small) = (-) (-Small) + (+Large) = (+) (-13) + (+5) = (-8) (-7) + (+9) = (+2) Rules for Subtracting Integers

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.

(-) - (-) = (-) - (+) = (+) - (-) = (-15) - (-7) = (-5) - (+6) = (+4) - (-3) = (-15) + (+7) = (-8) (-5) + (-6) = (-11) (+4) + (+3) = (+7)
