Free scientific calculator

This free calculator can perform simple and complex computations.

ESBCalc is a free scientific calculator that performs trigonometric, hyperbolic, and logarithmic functions. It has a "Paper Trail" option that shows you your calculations on a virtual paper tape like an accounting calculator. You can change and customize the color of the calculator's buttons and background using the Options menu. ESBCalc also functions as an ordinary calculator.

ESBCalc's interface is basic, but it's designed to resemble a handheld scientific calculator, so it'll be familiar to many users with science and engineering backgrounds. Clicking the "I" button on the calculator brings up a Read Me file that offers minimal help for using the ESBCalc but not for doing the math. For instance, it doesn't offer step-by-step information about how to compute trigonometric, hyperbolic or logarithmic functions. Users with this knowledge will know the proper sequence of buttons, but students new to complex mathematics might have difficulties. The Paper Trail option is a good feature and would be helpful for adding up long lists of data. We were able to perform basic math calculations with no trouble. We like that you can still use ESBCalc as an ordinary calculator, which makes it useful to a wider variety of people, but we wish it offered more help for using its higher math capabilities. A step-by-step user's guide in the Help file would be a good place for improvement.

ESBCalc is free, and it installs and uninstalls with no problems. This Windows program is a good option if you're looking for a free scientific calculator.
