This paper covers

• Data analysis: five-number summaries and outlier fences, the 68-95-99.7% rule and z-scores, least squares regression from summary statistics with residuals, and seasonal indices with trend-line forecasting.
• Recursion and financial modelling: flat-rate vs reducing-balance depreciation, reducing-balance loan recurrences and amortisation components, Finance Solver balances and total interest, and perpetuities vs annuities.
• Matrices: matrix products for revenue, determinants and inverses for solving simultaneous equations, transition matrices with state predictions and steady state, and Leslie matrix population modelling.
• Networks and decision mathematics: vertex degrees and Euler trails, minimum spanning trees, shortest paths, maximum flow-minimum cut, and project scheduling with critical paths, float and crashing.
