The blog reminded me of one of the Starting Points I included in the current fourth edition of About Teaching Mathematics. In her post, Nancy talks about helping her first graders understand the meaning of the equals sign. On equal grounds.A Tweet I read a few days ago led me to a blog post by Nancy Q. This allows one to work with functions and variables Syntactic form of the symbol, but at the moment of assignment). Variables is achieved not on the level of keywords such as, or specific forms of functions declaration, butĮssentially by the assignment operator that have been used to define the symbol (this is somewhat oversimplified),Īnd also to some extent by a type of global rule associated with the symbol (but again, it is decided based on the Mathematica differs from other programming environments in that the distinction between functions and Recomputation of the right-hand side, on a changed argument is a natural operation. Normally one uses Set (=) to define variables, and SetDelayed (:=) - to define functions, for which the The left-hand side is assigned the value that the right-hand side has at the moment of Main difference between the two assignment operators, since with Set, When the left-hand side appears somewhere in the program. So, with this kind of assignment, the right hand side is notĮvaluated at the moment of assignment, but is re-evaluated every time Time that x is encountered, by the value that y will have at that 'add to the global rule base a rule, which will substitute x every The literal equivalent is the SetDelayed command, for instance SetDelayed.

(:=) (semicolon plus an equal sign), say x:=y. This command has a literal equivalent Set: we couldĮquivalently write Set. The immediate assignment is performed with the equal sign (=), say x = y, which means 'assign to x the value that y There are two assignment commands in Mathematica: immediate and delayed assignment. Right-hand side when this is unevaluated. When you enter an equation in the form of F=A x+ b, you use this command the regular is used to define assignments, while is used to represent the left-hand side in the form of the

When you use this command, the solution or result of the command will not appear when you enter the equation.įor defining an equation or for testing if an equality is true. The SetDisplayed command defines an expression that must be manually displayed. In Mathematica, the Set defines an expression to be displayed upon execution so it can be checked for errors. The following commands are different ways of using the = sign. This sign does not just mean equals like it does in normal mathematics. In Mathematica, there are many different commands that involve the equals sign, =.
