Go to calculator →Logarithms are essential mathematical functions used in various fields, from science and engineering to finance. Understanding how to use the logarithm function on your calculator can significantly simplify complex calculations. This guide will walk you through the process, provide practical examples, and offer tips for efficient use.
Before diving into calculator operations, let’s briefly review what a logarithm is. A logarithm is the inverse operation to exponentiation. It answers the question: to what power must a given number (the base) be raised to produce another number?
The most common types of logarithms are:
Most scientific and graphing calculators have dedicated logarithm buttons. Look for:
Some calculators may require you to press a “2nd” or “shift” key to access these functions.
Example: To calculate log(100)
Example: To calculate ln(e)
If you need to calculate a logarithm with a base other than 10 or e, use the change of base formula:
log_b(x) = ln(x) / ln(b)
Example: To calculate log_2(8)
Mastering the use of logarithms on your calculator opens up a world of advanced mathematical operations. Whether you’re a student, professional, or math enthusiast, this skill will prove invaluable in various applications. Ready to put your new knowledge into practice?

Basic calculators typically don't have logarithm functions. You'll need a scientific or graphing calculator for these operations.
"log" usually refers to the common logarithm (base 10), while "ln" is the natural logarithm (base e).
Use the exponent function. For base 10, use 10^x. For natural antilog, use e^x or the "exp" button.
Some calculators combine functions. You might need to press a "2nd" or "shift" key to access "ln".
Yes, logarithms can be negative when the input is between 0 and 1.
