Calculators

If you currently own a TI-83 Plus or TI-84 Plus and you would like it to be programmed please include a check for $15 and ship your calculator to:

Chad Cargill's Calculator Programming
P.O. Box 160
Harrah, OK 73045

We will pay to ship it back, just make sure you include your address.

These new calculators from TI are exactly what you can buy in the store, with one exception. When you buy here, we open your new calculator and load equations and solvers in your calculator's memory which can easily be used to solve many problems on the ACT test. A packet explaining the use of each program (including screen shots) will be included with every calculator purchase.
Equations and solvers we load for you are the following:

  1. Midpoint Solver given any two points
  2. Distance Formula and Solver
  3. Right Triangle Solver - This program solves for the lengths of the three sides and the measure of the interior angles given any two sides, two angles, or a side and an angle
  4. Radical Reducer - This program reduces any positive radical to its simplified form
  5. Equation Solver for any Linear or Quadratic equation of 1 variable, 2 equations and two unknowns, or 3 equations and 3 unknowns.
  6. Prime Factorization Solver
  7. Quadratic equation and quadratic equation solver. When you enter A, B, and C, this program produces the values of X in simplified radical form and it handles imaginary numbers too.
  8. Pythagorean Theorem and Solver (Answer in Decimal and Simplified Radical form)
  9. Equation of a Line, Slope of a Line, Y-Intercept, and X intercept solver given two points, slope and a point, or slope and Y-Intercept
  10. Equation of a Circle
  11. TI-83 PlusCircumference and Area Solver for Circles
  12. Perimeter and Area Solver for Triangles
  13. Volume and Surface area Solver for Box, Cylinder, Sphere, Cone, and Doughnut
  14. Volume Solver for Pyramid and Prism
  15. Formulas for Area of a Trapezoid, Area and Circumference of a Circle, Volume and Surface Area of a Cylinder, Cone, and Sphere
  16. Greatest Common Factor Solver given any two numbers
  17. Logarithm Solver for base, term, or equal
  18. Midpoint Formula
  19. Midpoint Solver for Missing End when given one end and the midpoint but having to find the other end
  20. Polygon Solver - When the number of sides is entered, the program produces the sum of interior angles, sum of exterior angles, total unique diagonal, diagonal per vertex, triangles, interior angle, exterior angle, and central angle
  21. Definition of Rational and Irrational numbers
  22. Sequence and Series Solver - This program analyzes the five elements of any sequence or series: 1st Term, Last Term, Distance Between Term, Number of Terms, and Sum of Terms. Given any three of the above five critical elements, the program produces the answer to the other two
  23. Law of Sines and Cosines
  24. Sine, Cosine, and Tangent
  25. Solver using Sine, Cosine, or Tangent to find lengths of sides or angles
  26. Inequality Plotter
  27. Angle Terms
  28. Area Solver for Triangles, Rectangles, Parallelograms, Trapezoids, and Squares
  29. Perimeter, Area, and Diagonal Solver for Squares and Rectangles

KEY SELLING POINTS

  • TI-84 Silver EditionChad wrote some of the programs, downloaded some programs from public domain, and downloaded and altered some programs to make them work for ACT purposes. 
  • This process took Chad over 18 hours to do. 
  • We had over 3000 satisfied customers last year alone.
  • The calculator usually solves up to ¼ of the ACT math test for you in as little as 3 minutes.  If you get 15 of the 60 questions correct with your calculator and randomly guess on the remaining 45 questions with the odds of 1 in 5 correct, you will be at the median score for the state of Oklahoma in Math of 18.  If you are able to get 8 of the remaining 45 correct on your own and then randomly guess, you will be at a 22 in math. 
  • We warranty all new calculators for one year.  If it quits working, you send it to us and we send you a new one.
  • You get a lifetime warranty on the programs.  If a program ever gets messed up, stops working, or deleted, simply send the calculator to us with a note, and we’ll reset it, reload it, and ship it back to you all at no charge.
  • Free technical support on our website www.chadcargill.com by posting on our message boards.

The purchaser is responsible to validate the formulas and programs in the calculator.  Cargill Consulting, Inc. assumes no responsibility for errors in formulas or solvers or malfunctions of the calculator during a test.  All TI disclaimers and warranties apply to this calculator.   You should review ACT’s rules for calculator use before using this calculator on each test you take.  ACT can change calculator rules at any time.  If ACT changes the rules prohibiting the use of this calculator, your calculator is not refundable.   You are not purchasing the programs.  You are paying the $10 mark-up or $15 load fee for our 18 hours to load programs found in public domain, load programs we wrote, load programs we customized to fit ACT purposes, and produce the explanation document for you.
