A logarithm answers the question "what power do I raise the base to in order to get this number," so log base 10 of 1000 is 3. The browser-based scientific calculator evaluates logarithms and exponents directly, running entirely in your browser with nothing uploaded.
A logarithm is the inverse of raising a number to a power. If the base is 10 and 10 to the power 3 is 1000, then the log base 10 of 1000 is 3. The common logarithm uses base 10, and the natural logarithm uses the constant e, roughly 2.71828, as its base. Logarithms turn multiplication into addition, which is why they show up in everything from sound levels to earthquake scales.
The scientific calculator evaluates expressions with logarithms, exponents, square roots, trigonometric functions, and the constants pi and e, all with parentheses so you can build up a full expression. That lets you compute a log directly instead of reaching for tables. It runs locally in your browser, so the expressions you enter never leave your device.
Log usually means the common logarithm with base 10, while ln is the natural logarithm with base e.
Yes. The scientific calculator supports logarithms, exponents, roots, trig functions and parentheses together.
No. Every calculation runs in your browser.
