# U mag kunt geen formule voor de berekening
van een eerste of een tweede afgeleide, van
een bepaalde integraal, van een sommatie
(Σ), van een extremum (maximum/minimum),
van een nulpunt (Solve), RndFix of log ab
gebruiken als term in een log ab-berekening.
#In de invoermodus LINEAR en MATH krijgt u
verschillende resultaten wanneer twee of
meer machten in serie worden ingevoerd,
bijvoorbeeld: 2M3M2.
Invoermodus LINEAR: 2^3^2 = 64
Invoermodus MATH:
= 512
Dat komt doordat de modus MATH de
hierboven vermelde invoer inwendig verwerkt
als: 2^(3^(2)).
