Simple JavaScript Calculator
Here i have a very simple script for a JavaScript calculator
It is a pretty basic script that uses a text field to create the equation with the buttons and then equates the equation to show you the answer.
There is also a Memory Store (MS), Memory Recall (MR), and a Memory Clear (MC). For those of you that may require it
