Works like the CAPS-approved scientific calculators. SHIFT unlocks the yellow functions, ALPHA the pink letters (variables A–F, X, Y, M).
Try these
sin 30 → ½ 2SHIFTsin inverse trig √ 144
1 a b/c 3 + 1 a b/c 6 → ½, then S⇔D flips fraction ⇄ decimal
5 SHIFT x² → 125 8 nCr 3 → 56 5 SHIFT x⁻¹ → 120
Ans uses your last answer; start with + − × ÷ and it is inserted for you. ▲ / ▼ replay earlier calculations.
MODE → STAT for mean, standard deviation, quartiles and regression; EQN for simultaneous, quadratic and cubic equations; TABLE for f(x) tables. SHIFT MODE sets Deg/Rad/Gra, Fix/Sci and the decimal comma.
