Sigma Summit

Sigma Summit is a multiplayer math review game for Algebra 2. An Algebra 2 game show on series and the Binomial Theorem: arithmetic and geometric series, sigma notation, Pascal’s triangle and binomial expansions.

Skills: Sums of arithmetic series with S = n(a₁ + aₙ)/2, finding the last term, theater-seat and log-stack problems, finite geometric series with S = a₁(1 − rⁿ)/(1 − r), savings, bouncing-ball and growth problems, evaluating sigma notation, writing a series in sigma notation, Pascal's triangle, combinations nCk, number of terms and row sums, coefficients in (x + c)ⁿ and (ax + b)ⁿ, expanding binomials.

New problems every game, with Easy, Medium and Hard levels. Every miss shows a short explanation.
