# Abacus Formulas

Using formulas, you can create complex mathematical formulas without the hassle of coding.There are there distinct formula types based on the types of fields that they affect.

**Numeric Formulas**

Numeric formulas allow you to Create almost any numeric formula using mathematical expressions. The following calculations can be done easily with Numeric formulas:

Summating fields with one another.

Incrementally increasing fields.

Attributing the summation or average of a numeric calculation to the parent epic or parent issue.

Rounding results to the nearest whole number.

And more...

*Learn more by reading the ***Numeric Formula**** **documentation.

**Date Formulas**

Date formulas allow you to add or subtract duration values to your date fields within JIRA. The following calculations can be done easily with Abacus Date Formulas:

Calculating Due date based on other field values.

Calculating the duration difference between two date fields.

And more...

**Duration Formulas**

Duration formulas allow you to use duration fields to create calculations within your project. The following calculations can be done easily with Abacus Duration Formulas:

Add or Subtract two duration fields

Multiply or Divide two duration fields with one another or a duration field with a static number

Attribute duration calculations to the parent epic or parent issue

And more...
