If it has batteries, then it works!
2
I keep hitting on and nothing is happening....
Try darkening(2nd ) the screen first,
before replacing the batteries.
3
Message Batteries are low
Press clear.

I asked it for this square root..
If you take the square root of a negative number-
you get an imaginary number not a real number.
5
I wanted a fraction and it keeps giving me the
same answer
The decimal will not convert to a fraction-use
your place value rules to determine your
denominator.
6
It is putting E's in my answer
You must check the mode that the calculator is
in.
Your calculator needs to be stage left. Normal
should be highlighted instead of scientific.
7
I put in an equation to graph, but it did not
show up
Change window or zoom out.

There is no x ...
Any exponent can be written by and the power.
Your calculator can only do 2 without using .
9
Why can't it do 2-3?
A minus sign is an operation and a negative sign
is a direction. The calculator KNOWS the
difference, do you?
10
But the calculator said it was -4....
If you are trying to square a number be sure you
put parentheses in- your calculator knows its
Order of Operations and will do the exponent
before the multiplication!
11
It won't find the minimum value (maximum or
x-intercept)
Face your triangles toward each other!
Check your left and right boundaries- be sure you
have gone left enough and right enough around the
point in which you are looking at!
12
It won't find the intersection point
You have asked the calculator to identify a point
that does not exist---- NO SOLUTION!
13
I asked it to determine the regression line and
it won't
1. Check your Lists to be sure Number of data
points match
2. Be sure that the data is being pulled from the
right lists
14
Why won't it add the matricies
Check matrix dimensions when doing certain
operations addition and subtraction- dimensions
must MATCH multiplication- interior dimensions
must match
15
Why won't it graph?
Highlight and hit enter to cut on and off!
Be sure PLOTS are off when graphing lines
