{ (less or equal) Expr1 { Expr2 ⇒ Boolean expression List1 { List2 ⇒ Boolean list Matrix1 { Matrix2 ⇒ Boolean matrix See "=" (equal) example. Returns true if Expr1 is determined to be less than or equal to Expr2. Returns false if Expr1 is determined to be greater than 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 (greater than) Expr1 > Expr2 ⇒ Boolean expression List1 > List2 ⇒ Boolean list Matrix1 > Matrix2 ⇒ Boolean matrix Returns true if Expr1 is determined to be greater than Expr2. Returns false if Expr1 is determined to be less than or equal to Expr2. Anything else returns a simplified form of the equation. For lists and matrices, returns comparisons element by element. See "=" (equal) example. | (greater or equal) Expr1 | Expr2 ⇒ Boolean expression List1 | List2 ⇒ Boolean list Matrix1 | Matrix2 ⇒ Boolean matrix See "=" (equal) example. Returns true if Expr1 is determined to be greater than or equal to Expr2. Returns false if Expr1 is determined to be less than 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 >= ! (factorial) Value1! ⇒ value List1! ⇒ list Matrix1! ⇒ matrix Returns the factorial of the argument. For a list or matrix, returns a list or matrix of factorials of the elements. & (append) String1 & String2 ⇒ string Returns a text string that is String2 appended to String1. /= keys /= keys /= keys º key /k keys 122 TI-Nspire™ Reference Guide
