• The Linear input/output mode and Math input/output mode produce different results when

two or more powers are input in series, like: 2

M 3 M 2.

Linear input/output mode: 2^3^2 = 64

Math input/output mode: 2

32

= 512

This is because the Math input/output mode internally treats the above input as: 2^(3^(2)).
