	Changing the Computation Mode of the Box.
	1. Click anywhere in the existing Math Box to select it. A solid border appears around the Math Box to show that it is selected.
	2. Click the Mode Setting button on the TI-InterActive toolbar.
	3. Three options appear under the Computation Mode: Automatic - uses Exact where possible, but uses Approximate when your entry contains a decimal point. Exact - any result that is not a whole number is displayed in a fractional or symbolic form. Approximate - all numeric results, where possible, are displayed in decimal form.

	5. Click the Mode Setting button again, and change the Computation Mode back to Automatic, the original setting.
