![]() ![]() If you measure a radius of 2.35, multiply by 2 to find the diameter of the circle: 2 * 2.35 = 4.70 If your calculation involves a constant or an exact value as you might find in a formula, do not check the “auto-calculate” box.įor example, consider the formula for diameter of a circle, d = 2r, where diameter is twice the length of the radius. There are some cases where you would not want to auto-calculate significant figures.

You may also see BEDMAS, BODMAS, and GEMDAS as order of operations acronyms. PEMDAS stands for “ Parentheses, Exponents, Multiplication and Division, Addition and Subtraction” The acronyms for order of operations mean you should solve equations in this order always working left to right in your equation.
