About this tool

What does Scientific Calculator do?

Evaluate a safe mathematical expression. The workspace keeps the input and result together, making it easy to check the change before you use it elsewhere.

For example, you can evaluate a safe mathematical expression before putting figures into a plan or budget.

What you can control

Scientific Calculator stays deliberately simple: add the expression, run the tool, and review the result.

How to use Scientific Calculator

  1. 1

    Enter the expression you want Scientific Calculator to process.

  2. 2

    Review the expression and correct anything you do not want carried into the result.

  3. 3

    Run Scientific Calculator, check the answer against your inputs, and copy the result if you need it elsewhere.

Tips for a better result

  • Keep the entered figures nearby so you can recheck the Scientific Calculator answer and its assumptions.
  • Read the complete result rather than relying on the first line or preview alone.
  • Recheck the inputs and assumptions before using the result for an important decision.
