We can also create a list by entering the list elements manually. Lists are enclosed by braces, \) in incremental of \(di\). Parentheses, ( ), are used to group objects together, thus establishing priority of operations, e.g., (3+4)/2, which is different from 3+4/2. The standard arithmetic operations are +, -, *, /, and ^.įunction arguments are always enclosed by square brackets,, e.g., Sin, Sqrt, Log, Max, etc. Use the command Clear to clear all variables.Ĭhoose Quit Kernel from the Evaluation menu to quit the kernel, which clears all the defined variables.Īll Mathematica commands begin with a capital letter, such as Sin, Cos, Table, Integrate, Plot, etc. to remove any variable definitions, e.g., Clear clears the values stored by variables x and y, and a=. No need to say, the user-defined variable names should not be the Mathematica built-in names. Mathematica is case sensitive, e.g., the variable abc is not the same as Abc. Variable names cannot begin with numbers, e.g., 5name is not allowed But otherwise numbers can occur and there is no restriction on the length of a name, e.g., alpha123, beta, lambda, etc. Group cells that groups the input and output cells together.ĭouble click on the bracket of the group to hide and redisplay the group cells. To abort the evaluation, choose Abort Evaluation from the Evaluation menu, or press Alt+. Use a semicolon after the expression to suppress the output. Press Enter, instead, to create a new line in the input cell. To evaluate the expression, press Shift+Enter in the input cell. These cells are labeled In, Out, In, and so on. When you begin typing commands, you’ll notice that brackets appear on the right side of the notebook. Mathematica Notebooks are comprised of cells.
