This worksheet is the last in our series designed to encourage pupils to use calculator functions and buttons to carry out operations such as squaring, squaring rooting, using brackets, multiplying by pi, working with fractions and more.

In section A, pupils will write down the full calculator display to seven questions similar to those found in GCSE exam papers today. These answers will also be rounded to three significant figures. Then in section B, pupils will answer six worded questions, considering how to use their calculator to do so. Questions include finding the surface area of the earth; however, any formulae used are provided.
