take precedence over
multiplication and division.
# 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)).
