<p>Somehow x on my ti-89 got set to a value of 0 and I can't seem to change it back. Anyone know how to fix this? All my other variables are fine its just x.</p>
<p>Whatever value you want it set at, just enter it into the calculator and press enter. Then, press STO> (above the ON key) and press X. You now have a new value set for X.</p>
<p>No, he needs a way to clear the x variable. What you need to do is click one of your menu’s, doesn’t matter which one, and go to the one that is all the way to the right. On the drop-down, it will say ‘Clear all A-Z’. Hit that, and all of your variables are cleared.</p>
