#You cannot use a differential, quadratic differential, integration, Σ, maximum/minimum

value, Solve, RndFix or log ab calculation expression inside of a log ab calculation term.

#The Linear input mode and Math input mode produce different results when two or more powers are input in series, like: 2M3M2.

Linear input mode: 2^3^2 = 64

Math input mode: = 512

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