# Futher maths matrix

#1
I have a fx-991 EX class wiz calculator and I’m calculating inverse of matrix with that, is there any way to change the answer to the format 1/detA ( ) that form instead of having the determinant multiply in to the matrix? Hope someone can help me, thanks!

The manual is here:

If it is not stated, then it probably is not possible.

No, I don't even think that's possible with the CG50

If your matrix is MatA, then click OPTN then scroll to Determinant.

You can find the determinant of the matrix then multiply the inverse matrix by it to get it in that form.

For example if Det(MatA) = 7, then 7MatA-1 would be your matrix if you took out a factor of 1/7
