33s equation writing advice requested



Question 1 --I am trying to input some long equations into my 33s. It seems that if you input a long equation with an error near the beginning, the only way to fix it is to back up and erase everything you wrote afterward. What a lot of extra work! Is there any way around this?????

Question 2 -- When inputting an equation, I got the wrong answer when inputing test parameters. I turned off my calculator and returned later to find the error in the equation. Before changing anything, I ran my test again, using the same inputs, and this time got the corrct answer! How could this have happened?????


#1 - no, doesn't look like it.

#2 - user error most likely.


why the bakspace doesn't work in ALG mode?
