• The Linear input/output mode and Math input/output mode produce different results when
two or more powers are input in series, like: 2 , 3 , 2.
Linear input/output mode: 2^3^2 = 64 Math input/output mode:
2
3
2
= 512
This is because the Math input/output mode internally treats the above input as: 2^(3^(2)).
