Question about Texas Instruments TI-89 Calculator
I need to find out how to add and subtract feet and inches......
You can use the units menu (2nd > 3) to place a unit after some number you want to qualify as being an unit, or you can just type them in like 5_ft + 6_in. Note that you need to add on each part if you are doing mixed measurements; there is no _ft_in combination. So just add each manually - in your case you would do (5_ft + 6_in) - (2_ft + 8_in)
