(CALC)
• 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
32
= 512
This is because the Math input/output mode internally treats the above input as: 2^(3^(2)).
