1
Mixed fraction is supported in the Math input/output mode only.
*
2
For information about function input from the MATH function menu, see “Using the MATH
Menu” described below.
*
3
Tolerance cannot be specified in the Math input/output mode. If you want to specify
tolerance, use the Linear input/output mode.
*
4
For Σ calculation in the Math input/output mode, the pitch is always 1. If you want to specify
a different pitch, use the Linear input/output mode.

5
This is the number of bytes for a 2 × 2 matrix.
u Using the MATH Menu
In the Run-Matrix mode, pressing 4(MATH) displays the MATH menu.
You can use this menu for natural input of matrices, derivatives, integrals, etc.
• {MAT/VCT} ... displays the MAT/VCT submenu, for natural input of matrices/vectors
• {2×2} ... inputs a 2 × 2 matrix
• {3×3} ... inputs a 3 × 3 matrix
• {
m×n} ... inputs a matrix/vector with m lines and n columns (up to 6 × 6)
• {2×1} ... inputs a 2 × 1 vector
• {3×1} ... inputs a 3 × 1 vector
• {1×2} ... inputs a 1 × 2 vector
• {1×3} ... inputs a 1 × 3 vector
• {log
a
b} ... starts natural input of logarithm log
