Ubuntu users can install it with the standard sudo apt-get install qalculate command, while Fedora users have to run su -c "yum install qalculate-gtk".Īfter installing Qalculate!, GNOME users can launch it from the Applications -> Accessories menu, and KDE users from the Utilities menu. Like SpeedCrunch, Qalculate! is available in the software repositories of most distributions. If SpeedCrunch doesn’t impress you enough and you want even more from your calculator, such as solving calculus or trigonometry problems, turn to Qalculate!. You can then access the functions and constants from a tabbed right panel. To see a list of supported mathematical functions and pre-stored constants, click Settings -> Show Function List and Settings -> Show Constants List. You can change this behavior from the View menu. SpeedCrunch remembers expression history across sessions, but you can click Edit -> Clear History to hide all traces of using SpeedCrunch to do your homework.īy default, SpeedCrunch displays up to 20 decimal digits where applicable. Along with these variables, SpeedCrunch also remembers every expression you ever enter, and you can browse through the history of expressions by using the up and down arrow keys. To delete the value of a stored valuable, click Edit -> Delete Variable and then select the variable from the list. This means you can set x = 7 and y = 4 and then solve equations such as z = 4*x+5*y^2-17. For instance, if you enter 2^8-10+14*6, the answer, 330, is stored in ans, which means you can then enter ans*4-16.Īnother cool feature is variable storage. Whenever you compute any value with SpeedCrunch, the answer gets stored in ans. One of the most useful buttons on SpeedCrunch’s keypad is ans. Once installed, you can launch SpeedCrunch from the Applications -> Accessories menu if you’re running GNOME or from the Utilities menu on KDE. It’s available in the software repositories for most distributions, or you can grab the tarball from the project’s Download page. It runs not only on Linux but also on Windows and Mac OS X, and offers over 50 mathematical functions, unlimited variable storage, automatic completion, expression history, and more. SpeedCrunch is the lesser of the two beasts. From breaking down complex algebraic equations, to solving your calculus problems, to performing geometric computations and providing statistical answers, SpeedCrunch and Qalculate! are tools that offer quick solutions to difficult questions. Fish shell like syntax highlighting for Zsh.If I had had SpeedCrunch or Qalculate! during high school, finishing homework really would’ve been child’s play. Simple script to print the last 10 commands you ran in the current directory Includes 300+ optional plugins (rails, git, macOS, hub, docker, homebrew, node, php, python, etc), 140+ themes to spice up your morning, and an auto-update tool so that makes it easy to keep up with the latest updates from the community. □ A delightful community-driven (with 2,100+ contributors) framework for managing your zsh configuration. Jump quickly to directories that you have visited "frecently." A native Zsh port of z.sh with added features. Windows Calculator: A simple yet powerful calculator that ships with Windows □ ZSH port of Fish history search (up arrow) Kalker/kalk is a calculator with math syntax that supports user-defined variables and functions, complex numbers, and estimation of derivatives and integrals When comparing speedcrunch-nightlies and libqalculate you can also consider the following projects: What do I have to worry about if i am to install and use the Google Calculator on a deGoogled LineageOS?.I think the flatpak is preferred due to its significant size. It's a bit on the heavy side although it's definitely worth it if you're doing a lot of math. Sage is extremely powerful (you can do calculus, linear algebra, and more) but doesn't support units (that I know of), it's more geared toward advanced maths. One alternative is to use Jupyter notebooks, sometimes I work problems with Sage+Jupyter. This notepad aspect does seem useful though. It's fantastic for engineering and specially back-of-envelope calculations. It also converts units like 1kW x 1year = 31.55. It can do cool stuff like converting N (newtons) to kg.m/s^2 when you specify units as ?kg. One related app that I absolutely love is Qalculate! (yes, it has a built-in exclamation for default enthusiasm :) ) Note: I had this response typed up but didn't submit.
