How it works

The calculator evaluates a full expression using standard mathematical precedence: parentheses first, then exponents, then multiplication and division, then addition and subtraction. Functions such as sin, cos, tan, ln, log and square root apply to the value in the brackets that follow them. In scientific mode you can choose whether angles are read in degrees or radians.

How to use the Scientific Calculator

Enter the values requested by the tool and start with one realistic example. Read the result together with its unit or label, then change one input at a time if you want to compare options. Keeping a note of the original figures makes the calculation easier to check later.

A result is only as useful as the values and settings entered. Try a simple known example if you want to check your working.

Frequently Asked Questions

How do I switch to scientific mode?
Use the Standard and Scientific toggle at the top of the calculator. Scientific mode adds trigonometry, logarithm, power, root and factorial buttons.
Does it work with my keyboard?
Yes. You can type numbers and operators, press Enter to calculate, Backspace to delete and Escape to clear.
Are angles in degrees or radians?
You choose. In scientific mode there is a Deg and Rad toggle that controls how the trigonometry functions read angles.
