Overview
Wolfram Alpha is a computational knowledge service that converts natural language or mathematical input into a computational query for mathematical, scientific and related data issues.
Key features
- Calculating queries: submit mathematical or knowledge questions
- Result interpretation: view the calculation and the relevant background information
Suitable uses
Suitable for students, office staff and users requiring daily numerical estimates. For example, to compare the results under different input conditions, or to check the variable relationship of a computational problem.
Getting started
Define the calculation and units, then enter the parameters in the appropriate calculator. Read its formula, assumptions and rounding rules. For important results, test a set of known values to check the calculation.
Things to check
Different calculators may have different assumptions. Amounts, health and other important decisions need to be judged in the context of professional rules.
Pricing and availability
Account requirements, pricing, export limits and regional availability can change. Check the current official terms before using the service. This directory does not promise a particular free allowance or price.
