Free houghton mifflin math expressions software for windows

Math Expression Calculator 9.14 is a program for evaluating mathematical expressions involving multiple variables. With it you are able to type in an expression such as '235 + 15.5 * 6 - ( 225 - 12.75 )' and see the result instantaneously. It supports a lot of functions in addition to the basic operators. It can save the calculations history, you are ease to re-trace your previous calculations. You can free from the frustration when using an ordinary calculator.

Enhancements: includes user interface enhancements.

Its a fast equation parser/evaluator with parse-tree builder and user-friendly interface for parsing and calculation a run-time defined math expression.
The math expressions is represented as string in a function style
F(x1, x2,..., xn) =f(x1, x2,..., xn)
, where
F(x1, x2,..., xn) - declares number and names of the variables;
f(x1, x2,..., xn) - math expression may contain:
-variables x1, x2,..., xn and numbers,
-arithmetic operations + - * / ^,
-supporting a large set of math functions: sqrt, sin, exp, cos, tan, ln, abs, acos, asin, atan, cosh, log10, sinh, tanh,
-constants e= 2.71828182845904 and pi= 3.14159265358979, and
-user defined functions and constants.
For example:
F(x, y) = 3*x^2+y^2+e/4,
F(x1, x2, y) = (x1-sin(x2))/y,
F()=5+6+pi.
Algorithm, which is used here, has been developed and implemented by Easy Math Solution and has different binary (static link library, dynamic link library and COM) implementation and programming approach (procedural and object oriented). It allows using EquTranslator in C/C++, C#, Delphi, VB and other languages and systems that can understand dll and COM.

Add context menu command to rename selected files using regular expressions Rename Regular Expression will help you to rename selected files much more easier using regular expressions. Case-sensitivity, global replace, group expressions, number sequencing and more.
