- 2Specify the variable to solve for
- 3Supports linear, quadratic, and simultaneous equations
💡Tips & Knowledge
- •For ax²+bx+c=0, the discriminant D=b²−4ac tells you the number of solutions: D>0 two, D=0 double root
- •Simultaneous equations are solved via Gaussian elimination — handy for manual calculation checks before studying matrices
- •Substitute values from physics or chemistry formulas to solve for unknowns
