= (equal) = key Expr1 = Expr2 ⇒ Boolean expression List1 = List2 ⇒ Boolean list Matrix1 = Matrix2 ⇒ Boolean matrix Example function that uses math test symbols Returns true if Expr1 is determined to be equal to Expr2. Returns false if Expr1 is determined to not be equal to Expr2. Anything else returns a simplified form of the equation. For lists and matrices, returns comparisons element by element. Note for entering the example: In the Calculator application @ on the handheld, you can enter multi-line definitions by pressing · instead of at the end of each line. On the computer keyboard, hold down Alt and press Enter.

Returns true if Expr1 is determined to be not equal to Expr2. Returns false if Expr1 is determined to be equal to Expr2. Anything else returns a simplified form of the equation. For lists and matrices, returns comparisons element by element. Note: You can insert this operator from the keyboard by typing /= < (less than) Expr1 < Expr2 ⇒ Boolean expression List1 < List2 ⇒ Boolean list Matrix1 < Matrix2 ⇒ Boolean matrix Returns true if Expr1 is determined to be less than Expr2. Returns false if Expr1 is determined to be greater than or equal to Expr2. Anything else returns a simplified form of the equation. For lists and matrices, returns comparisons element by element.
