This command has a literal equivalent Set: we could equivalently write Set x,y. The immediate assignment is performed with the equal sign (), say x y, which means 'assign to x the value that y has right now'. Click the x button in the formatting menu that appears, or use the keyboard shortcut. There are two assignment commands in Mathematica: immediate and delayed assignment. A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems.
