How to use the Advanced Math menu on the TI-84
The Advanced Math menu helps you solve problems such as cube roots, the x‑th root, and logarithms with a custom base (logBASE). Here is how to reach and use it:
- On the calculator page, press the MATH key (just under the ALPHA key).
- The Math Menu opens across three columns: MATH, NUM, and PROB.
- MATH column: fraction‑to‑decimal and decimal‑to‑fraction conversion,
³√((cube root),ˣ√(x‑th root), andlogBASE(log base n). - NUM column:
abs((absolute value),round(,iPart((integer part),fPart((fractional part),int((greatest integer),min(,max(,lcm((least common multiple), andgcd((greatest common divisor). - PROB column:
rand(random number),randInt((random integer),nPr(permutations),nCr(combinations), and!(factorial).
Graphing and statistics in the online TI-84
Beyond the Math menu, the emulator covers the full workflow you would use on hardware. To graph, press Y=, type your function, and press GRAPH; use TRACE and ZOOM to explore the curve. For data, open the statistics suite to run 1‑Var and 2‑Var stats, regressions, and probability distributions. Need to solve an equation symbolically? The AI equation solver shows every step.
Practical uses of the online TI-84
- Exam preparation: Approved for major standardized tests such as the SAT, AP, and PSAT/NMSQT — always confirm against the official College Board calculator policy.
