History[ edit ] An early experimental Chinese keyboard with many keys was developed by researchers of National Chiao Tung University in Taiwan, but it never became mainstream. Chinese input methods predate the computer.
Matrices in QuickMath can be as complicated as you like.
They can contain numbers only, as in the above example, or they can involve complicated mathematical expressions using pro-numerals and functions. When you are entering matrices, the rows and columns do not have to line up - as long as each row is on a new line and elements are separated with commas, QuickMath will know what you mean.
How do I enter cube roots, fourth roots, etc? To find the square root of something, use the sqrt function.
How do I enter powers? How do I divide fractions? Before you enter a quotient of two fractions, make sure you know how to enter fractions properly. Whenever you are dividing one fraction by another or indeed a fraction by anything else make sure you enclose each fraction in a set of brackets.
How do I multiply fractions? Before you enter a product of two fractions, make sure you know how to enter fractions properly.
Whenever you are multiplying two fractions by one another or indeed one fraction by anything else make sure you enclose each fraction in a set of brackets. How do I enter fractions? One of the biggest problems people have using QuickMath is knowing how to enter fractions properly.
This section will explain precisely how to enter fractions so that they are interpreted correctly by QuickMath. Let start with a simple fraction: This is how this fraction should be entered into QuickMath: If in doubt, always put brackets around the entire numerator and the entire denominator.
What is an equation? You need to enter an equation whenever you use a command from the equations section, but not in the algebra or calculus sections.
These sections require an expression only. I sent my question, but I got a timeout message. This is plenty for most calculations, but occasionally your time will run out before the question is answered. When this happens, you will receive a timeout message.In Descartes was the first to unite the German radical sign √ with the vinculum to create the radical symbol in common use today.
The symbol used to indicate a vinculum need not be a line segment (overline or underline); sometimes braces can be used (pointing either up or down).

Keyboard shortcuts are a brilliant time-saver; it's much easier to tap two or three keys at once than to go hunting through nested menus. But shortcuts depend on knowledge and muscle memory.

To insert a square root (a radical), you can click on the "√" button next to "A B C" on the Desmos keyboard. You can also type "sqrt" in the expression line, which will automatically convert into √ To enter the cubed root symbol from the Desmos keyboard, click on FUNCTIONS and then Misc.
It depends on your operating system, and language settings in your operating system, but if you're using windows you can enter unicode characters with the following directions.
