• Data structures: sets, lists, Arrays, Vectors, Matrices, ...
Maple contains over a thousand symbols. For some numbers, operators, and
names, you can press the corresponding key, for example, 9, =, >, or x. Most
symbols are not available on the keyboard, but you can insert them easily
using two methods.
To insert a symbol, you can use:
• Palettes

Palettes
Palettes are collections of related items that you can insert by clicking or
dragging. Palettes contain:
• Numbers and constants, like i (the imaginary unit), π, and ∞. For example,
