Cramer's Rule/Historical Note

Historical Note on Cramer's Rule

Cramer's Rule was first presented by Gabriel Cramer in $1750$.

While it can be used to solve any system of linear simultaneous equations, it needs many more mathematical operations than Gaussian elimination, hence it is generally used only for small $n$.
