Carry out calculations with more than one step using brackets and the memory; use the square root and sign change keys. Carry out more difficult calculations effectively and efficiently using the function keys for sign change, powers, roots and fractions; use brackets and the memory. Use a calculator efficiently and appropriately to perform complex calculations with numbers of any size, knowing not to round during intermediate steps of a calculation; use the constant, π and sign change keys; use the function keys for powers, roots and fractions; use brackets and the memory. Use an extended range of function keys, including the reciprocal and trigonometric functions. Use calculators to explore exponential growth and decay, using a multiplier and the power key. Use calculators, or written methods, to calculate the upper and lower bounds of calculations in a range of contexts, particularly when working with measurements.
Enter numbers and interpret the display in different contexts (decimals, percentages, money, metric measures).

The Apprentice Business Game

Enter numbers and interpret the display in different contexts (extend to negative numbers, fractions, time). Use standard index form, expressed in conventional notation and on a calculator display; know how to enter numbers in standard form. Calculate with standard index form, using a calculator as appropriate.
