Questions include evaluating expressions with brackets and multiplication, subtraction of mixed numbers and large differences, converting decimals to fractions, prime number identification, working with unit conversions, and using multiplication and rounding to one decimal place. Geometry tasks ask for area from given dimensions, interpreting a net to name a 3D shape, and finding a missing angle. Arithmetic word problems conclude with solving for unknown factors and reversing a chocolate consumption scenario, plus an expression evaluation
