Creating Variables

This in an introduction to creating variables in MathStudio's scripting language. Like other scripting languages, MathStudio uses variable names to store and refer to values.

However unlike other scripting languages, variables do not need to have a value assigned to be used. Variables can be used to create algebraic expressions or set to a value such as the number.

Variables must start with a lowercase, uppercase or underscore and can include numbers but not spaces. The @ symbol followed by an underscore (_) in a variable name is used to denote a subscript. Strings can be set to a value when preceded by the @ symbol.

Examples

a=8 a^2
a=123 b=456 a+b
f(x)=x^2 f(5)
a=x*x b=y*y a+b

Subscripts

x@_y

String Variables

@"Long Variable Name" = 12
@"Long Variable Name"^2
