Hi, I have a Casio fx 991 ex classwiz
The "syntax error" message that you are seeing on your Casio fx-991EX ClassWiz calculator is likely caused by the fact that the calculator does not support the use of decimal values in the exponent. The calculator can only accept integers (whole numbers) as exponents.
To work around this issue, you can try rounding the decimal value of the exponent to the nearest whole number. For example, if you need to calculate 1x10^7.2, you can round the exponent to 8 and calculate 1x10^8 instead. This will give you a close approximation of the desired result.
Alternatively, you can use a different calculator or software that does support the use of decimal values in the exponent. This will allow you to calculate the value more accurately.

I believe the rubber roller that feeds the paper
i don't know this particular calc very well, but on most calcs, the paper feeds between the rubber one and a plastic idler roller that is on a shaft below the rubber one. if you can see the rubber roller turning, check the plastic one as it can sometimes slide to one side or the other, and bind up causing paper to not feed. you can usually get at it with a small screwdriver or something like that and center it back and that will take care of problem.

Rank of a matrix
The row rank of a matrix is the maximum number of linearly independent rows.
The column rank of a matrix is the maximum number of linearly independent columns.
However, it can be shown that for any matrix A,
row rank (A)=column rank (A).
It is called the rank of A. The rank of an mXn matrix is less than the minimum of m and n
rank( A) less than or equal to min( m,n)
Note. This calculator cannot determine for you the rank of a matrix. The matrix operations available on this calculator are limited, and the calculator cannot handle matrices with dimensions higher than 3X3
