To perform a calculation, simply enter your mathematical expression and press Solve.

The result along with the steps taken to reach it will appear above.

The following sig fig rules are used:

• Addition (+) and subtraction (-) round by the least number of decimals.
• Multiplication (* or ×) and division (/ or ÷) round by the least number of significant figures.
• Logarithm (log, ln) uses the input's number of significant figures as the result's number of decimals.
• Antilogarithm (n^x.y) uses the power's number of decimals (mantissa) as the result's number of significant figures.
• Exponentiation (n^x) only rounds by the significant figures in the base.
• To count trailing zeros, add a decimal point at the end (e.g. 1000.) or use scientific notation (e.g. 1.000 × 10^3 or 1.000e3).
• Zeros have all their digits counted as significant (e.g. 0 = 1, 0.00 = 3).
• Rounds when appropriate, after parentheses, and on the final step.
