🎓 Your graphing calculator 84 for high school and college students.
✨ Includes all the commands and functions for advanced math, lists, statistics, distributions, stat plots, and more.
👆 Use the arrow keys or your fingers to navigate — same layout you already know.
📚 Covers everything you need: Pre-Algebra, Algebra 1 & 2, Pre-Calculus, Calculus, Statistics, SAT & ACT prep.

🚀 BETTER THAN A HANDHELD
• Taculator 84 is 100X faster than a physical graphing calculator because it uses the full calculation power of your phone, while handheld calculators like the TI 84 or Casio are often slow.
• High-resolution graphing window: make sharper, more beautiful graphs.
• Your new 84 calculator weighs nothing and is always in your pocket.
• Share your calculations with friends as a text message or email.
• No more dead batteries, no more replacing a lost TI84.

🧮 Math Functions
• Scientific calculator with all basic arithmetic and advanced functions.
• Ability to scroll through history and copy previous calculations.
• Complex numbers support.
• Probability functions: nPr, nCr, factorial, random numbers.
• Enter fractions easily.
• Convert angles and use DMS format.

📈 Graphing Functions
• Graph every function you want and trace for X- and Y-values.
• Calculate intersection, zero, minimum, maximum, integral, and derivative.
• Switch between full-screen graphs and normal mode.
• Zoom in and out with your fingers and adjust the window settings.
• Graph statistical plots like histogram, box plot, scatter plot, xy-line plot.
• Draw vertical, horizontal, tangent, and circle.

🔢 Matrix Calculator
• Store matrices and reuse them using shortcuts like [A], [B], [C],...
• Matrix arithmetic: scalar multiplication, addition & subtraction, multiplication, power of a matrix.
• Calculate transpose, determinant, dimension, inverse matrix, row echelon form, reduced row echelon form, identity matrix, cumulated sum.

📊 List, Statistics, and Distribution
• Use the stat list editor to enter your list values.
• Perform 1- and 2-Variable statistics.
• Use lists to calculate84 min, max, mean, median, sum, product, standard deviation, variance.
• Find best-fit regressions: LinReg (ax+b), LinReg (a+bx), QuadReg, CubicReg, QuartReg, LnReg, ExpReg, PwrReg, Logistic, SinReg.
• Perform statistical tests: Z-Test, T-Test, 2-SampleZTest, 2-SampleTTest, Ti84, 1-PropZTest, 2-PropZTest, ZInterval, TInterval, 2-SampleZInterval, 2-SampleTInterval, 1PropZInterval.
• Calculate various distributions: Normalpdf/cdf, invT, Tpdf/cdf, χ²pdf/cdf, Fpdf/cdf, Poissonpdf/cdf, Binompdf/cdf, Geometpdf/cdf.

💡 Command Catalog & Syntax Help
• Built-in Catalog & Help section with all the commands you need.
• It provides you with syntax help, examples, and possible error messages.
• Enter a command and the app will show you the right syntax next to the cursor.
