Evaluate piecewise functions in VBA
So, if a Dominican needs to calculate the taxes that will be charged to them monthly, they should take pencil and paper, compute the annual amount of income and apply the corresponding formula, or they can use the following code in conjunction with VBA Expressions and get their result in a simple way.

Solving systems of linear equations with VBA
Systems of linear equations have been taught since high school, they are of utmost importance in mathematics. Although Excel is possible to solve, manually, equations using matrix inverse and matrix multiplication. Today we will show you a practical way to solve such problems using VBA Expressions.

Advanced CSV filtering through VBA
After this publication, which details the reason why VBA Expressions turned out to be the most feasible option to solve the problem of integrating an expression evaluator with CSV Interface, it is time to address the process of integrating the evaluation capabilities and the ease with which this goal was achieved.

Evaluating expressions from strings in VBA
After a long search for something similar to the above, I decided to experiment and test the veracity of a warning that read: "... rather, it evaluates the infix expression directly. This approach is slightly more complicated than the traditional one". Then, I chose to develop an evaluator with its own grammar and a different approach to handle mathematical expressions. The solution I came up with is so called VBA Expressions. With VBA Expressions we can evaluate a variety of mathematical expressions, being able to work with arrays defined by text strings as in Java. A notorious feature is the ability to work with variables (Pi.e * 5.2Pie.1 + 3.1Pie), constants (3pi+ln(2e)), floating point numbers ((1.434E3+1000)*2/3.235E-5) and Boolean values (x>0 & Sqr(x-Ln(2))>=3 | tan(x)<0).
