Integer and Negative Number Calculator
Add, subtract, multiply, and divide integers (whole numbers) including negative numbers.
Use numbers and + - * / ( )
= -15 + 12 + -22 * -37
= -15 + 12 + 814
= 811
This calculator allows you to add, subtract, multiply, and divide integers, including negative numbers.
It shows step-by-step calculations, with sign changes for subtracting negative numbers. You can use it for adding, subtracting, multiplying, and dividing positive and negative whole numbers, as well as decimals. It also handles equations with parentheses.
Examples:
| Input | Result |
|---|---|
| -20 - -92 + 28 | 100 |
| (-20) - (-92) + 28 | 100 |
| -20 - (-92 + 28) | 44 |
| 24 * (77 - 15) + 12 | 1500 |
| (42 + 10) / -2 + 12 | -14 |
| (36+ 12) * 3 + (2 * 7) / 4 | 147.5 |

Adding Integers
If signs are the same, keep them and add the numbers.
| Method | Example |
|---|---|
| (+) + (+) = (+) | 30 + 15 = 45 |
| (-) + (-) = (-) | -30 + -15 = -45 |
If signs are different, take the larger number and subtract the smaller number from it. Then use the sign of the larger number.
| Method | Example |
|---|---|
| (-larger) + (+smaller) = (-) | -20 + 7 = -13 |
| (-smaller) + (+larger) = (+) | -5 + 12 = 7 |
Subtracting Integers
To subtract integers:
| Method | Example |
|---|---|
| (-) - (-) = (+ or -) | -12 - (-9) = -12 + 9 = -3 |
| (-) - (+) = (-) | -11 - 5 = -16 |
| (+) - (-) = (+) | 4 - (-3) = 4 + 3 = 7 |
| (+) - (+) = (+ or -) | 12 - 15 = -3 |
Multiplying Integers
If the signs are the same (both positive or both negative), the product is positive.
If the signs are different, the product is negative.
| Method | Example |
|---|---|
| (+) * (+) = (+) | 5 * 4 = 20 |
| (-) * (-) = (+) | -3 * -6 = 18 |
| (-) * (+) = (-) | -2 * 9 = -18 |
Dividing Integers
The rules are similar to multiplying integers:
If the signs are the same (both positive or both negative), the quotient is positive.
If the signs are different, the quotient is negative.
| Method | Example |
|---|---|
| (+) / (+) = (+) | 20 / 5 = 4 |
| (-) / (-) = (+) | -18 / -3 = 6 |
| (-) / (+) = (-) | -24 / 8 = -3 |
