If you have mastered matrix manipulations on the TI calculators, it should be a breeze to learn the same on the Casios.
A. Define the matrix (Create it)
Press [SHIFT][QUIT] to return to the list of matrices to create new ones
Operations on matrices
Once you have one matrix, you can do operations on it: Calculate the determinant (if matrix is square), calculate its inverse, transpose, augment it, fill it, etc..
[OPTN][F2:MAT] (MAT) [Alpha] A ^2 [EXE]
Product of two compatible matrices MatAXMatB
[OPTN][F2:MAT] (MAT) [Alpha] A [* ) (MAT) [ALPHA] B [EXE]
Hope it helps.
Thank you for using FixYa.

To calculate the reciprocal of a numerical value you can use
1 [/] 13 [EXE] result is 0.07692307692 or
13 [EXE] to have 13 in Ans memory (displayed) and [SHIFT][ ) ] [X to -1] [EXE].
For such a simple number as 13, calculating its reciprocal the second way seems ridiculous, but if the number is already displayed the second method is the only efficient one if you do not want to copy the result on a piece of paper and retype so as to calculate its reciprocal.

The inverse of a natural logarithm (ln) is the exponetial (e^x). Both share the same physical key [LN] pour ln and [SHIFT] [LN] (e^x) for the exponential.
Syntax is : [ln] 3 [EXE] gives 1.098612289
exponential of 4: [SHIFT][LN] 4 [=] 54.59815003
The inverse of decimmal logarith is raise 10 to a power. Both share tha same physical key [LOG]
log of 6 : [log] 6 [=] result is 0.7781512504
antilog of 0.77: [SHIFT][LOG] 0.77 [=] result is 5.888436554
For more complicated arguments (expressions) it may be a good idea to use parentheses to enclose the arguments of functions.

There is no button but a menu tab.
In Run screen, enter the number whose factorial you want to calculate ( number can be at most equal to 69), press [OPTN][F6] to get to next page of menus.
