Question about Texas Instruments TI-89 Calculator
For example when I input:
instead of the expected 2x
also, if I integrate:
instead of x^2/2
What you do is go to the home screen and hit f6 and hit 'clear a-z' that will clear all variables from being numeric variables.

Probably a value stored in the "x" variable (guessing x=1)
try the following, type or look for the "Define" function: Define X=X and see what happens, also try Cleaning the variables "F6>cleanup, etc" as a last resource do factory reset, but first archive your important files (not very recomended as some of them may contain the variable's value and just not solve this)
