(MAT) (Mat) (A) (MAT) (Mat) (B) .
• This will display the MatAns screen with the calculation results.
Note: "MatAns" stands for "Matrix Answer Memory".
7. Perform the next calculation (MatA + MatB): (MAT) (Mat)
(A) (MAT) (Mat) (B) .
Matrix Answer Memory
Whenever the result of a calculation executed in the MAT Mode is a
