It covers solving equations involving fractions and unknowns on both sides, changing the subject of a formula, and simplifying or factorising algebra. The checklist also includes data handling from sampling and bias to frequency tables, averages, outliers, and line of best fit, plus graphing skills for grouped data and straight-line graphs, along with percentages, decimals, and fractions.","FHS Mathematics Department  \nYEAR 9 – checklist  \n| Indices and standard form | ☺ | 􀀮 | 􀀯 |\n| --- | --- | --- | --- |\n| Use index laws to simplify
