    Get the most from your calculator

    Calculators are an invaluable tool when doing maths. As a student you need to become proficient at using your calculator. An important part of this process is learning how your calculator carries out certain calculations. While calculators are an important tool for doing maths, you still need to understand how to do calculations without a calculator and to understand if the results of a calculation are reasonable or not.
    You’ll find instructional videos and PowerPoints, and activities here to help you get the most out of your calculator.
