In equation mode you can write mathematical expressions and Let's Crunch It will evaluate them for you. These calculations are fully dynamic and results will change when their inputs change.
Let's Crunch It has many built-in functions that you can use when in equation mode. You can also reference the value of different variables (called "primitives") when in equation mode by using square brackets around the name of the primitive, e.g. [Primitive Name].
Example equations:
1 + 6 * 10
Sqrt(64) + Sin(2 * Pi)
[Inflation] * 2
Below is a comprehensive list of functions supported by Let's Crunch It.
