Arithmetic And Radical Operators Since in mathematics x = y has four diﬀerent meanings, (1) deﬁnition: deﬁnes functions or notation, for example, in the expression f ( x ) = x 2 + 1, one deﬁnes a function f by an expression x 2 + 1 . (2) assignment: assigns value of y to x; like in the sentence “set x = y. ..’ (3) logical equal: x is equal to y logically; like in the sentence “if x = y . ..”. (4) result of computation: like “ 4 + 5 = 9” here 9 is result of adding 5 to 4. Mathcad uses = as execution command, that is to tell Mathcad to compute the value. It uses (:=) for assignment and deﬁnition, and (boldface = ) for logic equal....
