Albertsoft.com PROVIDES:  MATH (algebra) SOFTWARE  and  FREE Formula, STAT Functions and Systems of EQUATION Solving.

OTHER PRODUCTS:    piano/organ/keyboard chord reference  

 NOTE: for Microsoft Windows only.

Solve formulas calculator:  Solve algebraic formulas and equations numerically and symbolically. They can be up to two lines in length and of unlimited number. The solve for variable can appear numerous times, be highly nested within parentheses and/or mathematical functions and be more than one character in length. The variables may be alpha-numeric or greek symbols or a combination of both.

Solve quadratic equations calculator: Solve quadratic equations (graphically).

Solve non linear equation systems  calculator: Solve systems of non-linear equations (graphically).

Solve linear equations calculator: Solve systems of linear equations (up to five ).

Evaluate formulas calculator: Evaluate algebraic formulas.

Statistics calculator: (s, Sx, Sx^2, m, and linear regression).

Derive functions calculator: Derive functions (polynomial curve fitting). This app provides the ability to find the value of x required to obtain a needed value for y.

Graphics  calculator: Graphics mode (plot functions and solve equations).

Built in programming language for mathematics. Unlike programming on some calculators in which you are only programming a series of keystrokes, this one allows you to write programs that can manipulate formulas, solve equations that might not ordinarily be solvable by regular methods, and much more. 

Scientific continual results calculator

Scientific operator precedence  calculator
