Using A Calculator

Akopọ

A calculator is only as accurate as the person using it. Knowing how to enter a calculation correctly, use brackets and the power and root keys, and read the display sensibly is what turns a calculator from a source of mistakes into a reliable tool.

In this lesson you will use a calculator efficiently, enter values and operations in the right order, and interpret the display, including rounded answers and numbers shown in standard form.

Awọn Afojusun

  1. Use a calculator efficiently.
  2. Enter values appropriately on a calculator.
  3. Interpret the calculator display appropriately.

Akọ̀wé Ẹ̀kọ́

In the calculator paper, most lost marks come from mis-entered expressions, not from the mathematics. A few good habits with brackets and the display protect a lot of marks.
