Pioneer Calc
Three free calculators that work like the ones students use: a TI-84 Plus CE (graphing and statistics), a TI-30XS MultiView (scientific, with stacked fractions), and a TI-30XIIS (two-line scientific). Same keys, same menus, same answers, on a laptop or a phone.

TI-84 style: where to find it
| Normal probability | 2nd VARS → 2:normalcdf( |
| Inverse normal (z*) | 2nd VARS → 3:invNorm( |
| t critical value / t probability | 2nd VARS → 4:invT( or 6:tcdf( |
| Binomial / Poisson | 2nd VARS → A, B / C, D |
| Enter data in lists | STAT → 1:Edit… |
| Mean, Sx, five-number summary | STAT → CALC → 1:1-Var Stats |
| Regression line, r | STAT → CALC → 4:LinReg(ax+b) |
| Hypothesis tests & intervals | STAT → TESTS |
| Answer as a fraction | MATH → 1:►Frac |
| nCr, nPr, factorial | MATH → PROB → 3, 2, 4 |
| Store a value in A | STO→ ALPHA MATH |
| Clear all lists | 2nd + → 4:ClrAllLists |
| Switch to degrees, fix decimals | MODE |
| Find any command A–Z | 2nd 0 (CATALOG) |
TI-30XS style: where to find it
| Type a fraction (stacked) | n/d, numerator, ▼, denominator, ▶ |
| Mixed number | 2nd n/d |
| Switch answer: fraction ↔ decimal | ◄ ► (toggle) after enter |
| Square root / nth root | 2nd x² / 2nd ^ |
| Scientific notation | ×10ⁿ |
| Previous answer | 2nd (−) (ans) |
| Store in x, y, z… | sto→ x yzt abc (press again for y, z, t…) |
| nCr, nPr, factorial, random | prb |
| Enter data in L1–L3 | data |
| Mean, Sx, five-number summary | 2nd data → 1:1-Var Stats |
| Regression line, r | 2nd data → 2:2-Var Stats (a, b, r) |
| Normal / binomial probability | 2nd data → ▶ DISTR |
| Table of values for f(x) | table |
| Degrees / radians, fix decimals | mode |
TI-30XIIS style: where to find it
| Fraction 3/4, mixed 2 1/3 | 3 A b/c 4 · 2 A b/c 1 A b/c 3 |
| Fraction ↔ decimal | 2nd A b/c (F◄►D), then = |
| Mixed ↔ improper | 2nd x⁻¹, then = |
| Previous entries | ▲ ▼, edit, = |
| Degrees / radians | DRG, ◀▶, = |
| Fix decimals / sci notation | 2nd EE (FIX) · 2nd , (SCI/ENG) |
| Store in A–E | STO▸, pick a letter, = |
| nPr, nCr, !, random | PRB |
| Start 1-var or 2-var stats | 2nd DATA (STAT) → 1-VAR / 2-VAR, = |
| Enter data | DATA, value ▼ FRQ ▼ … then = |
| Mean, Sx, a, b, r | STATVAR, ◀▶ |
| Clear data / leave stats | 2nd DATA → CLRDATA · 2nd STATVAR |
TI-84 style: not included (yet)
Graphing (Y=, WINDOW, GRAPH, TABLE), matrices, complex numbers, and programs. Those keys show a short notice instead.
TI-30XS style: not included (yet)
The constant feature (K), DMS minutes/seconds entry, list formulas, and CLASSIC display mode.
TI-30XIIS style: not included (yet)
The constant feature (K), DRG► conversion, minutes/seconds entry, and the X′/Y′ predictions in STATVAR.
Using your keyboard
Click the screen, then type: digits, + − * / ^ ( ) and . work as expected. Enter = enter, Backspace = delete, Esc = clear, and the arrow keys move the cursor. On the keyboard, − at the start of an entry types a negative sign; on the calculator keys, use (−) for negatives, just like the real calculator.
Your lists, stored variables, and settings are saved in this browser, so they're still there when you come back.
