Chalk 1.3.2 Description:
Although macOS has a built-in calculator, there are times when its three working modes (i.e. basic, scientific, programmer) are just not enough for the task at hand.

In other cases, you may want to plot a mathematical expression, and the macOS calculator is definitely not equipped for such tasks.
