# Online Scientific Calculator

This is a formula calculator. Enter your expressions in the same order as you would write them on paper. Then press '=' to display the result.

Use parenthesis to alter the order of operations or to specify function parameters.

Example of a valid expression: (-3+sqrt(16/4))/4

Results are displayed as fractions when possible, as well as in their floating point approximation.
