Arithmetic Sequence Calculator
Calculate the nth term, sum of n terms, or position of a term in an arithmetic sequence. Ideal for students and professionals working with linearly changing data.
Fill in the required fields to see your result.
Algebra
2x2 System of Equations Solver
Solve a 2×2 system of linear equations in the form a₁x + b₁y = c₁ and a₂x + b₂y = c₂ using Cramer's rule. Returns the x-coordinate of the intersection of the two lines; foundational for any problem with two unknowns and two constraints.
