You can create many practical Visual Basic applications in solving secondary school mathematics. Among them is simultaneous equations. You can create Visual Basic applications to solve linear simultaneous equations and non-linear simultaneous equations. Simultaneous equations are equations that involves two or more unknown variables. There must be as many equations as the number of unknown variables in order for us to solve the problem.
We have written two simultaneous equations solver using Visual Basic 6, one is linear and the other one is non-linear. learn more by following the links below:
