# Integer and Negative Number Calculator

Add, subtract, multiply, and divide integers (whole numbers) including negative numbers.

Use numbers and + - * / ( )

**Answer:**811

**Step by step:**

= -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 |

## How to use this calculator?

- Enter your math equation. You can use numbers and + - * / ( ).
- Click the "Calculate" button.
- Get your Answer and see the step-by-step calculation.

If you want to clear the input field and the result, click on the "Clear" button. However, it is not necessary as you can enter another equation and simply click "Calculate" again.

## 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 |
