Keyboard Math Operations

Using Lists with Math Operations

Math operations that are valid for lists return a list calculated element by
element. If you use two lists in the same expression, they must be the
same length.
+ (Addition), N (Subtraction), ä (Multiplication), à (Division)
You can use
+
(division, ¥) with real and complex numbers, expressions, lists, and
à
matrices. You cannot use
valueA + valueB
valueA ä valueB

Trigonometric Functions

You can use the trigonometric (trig) functions (sine, ˜; cosine, ™;
and tangent, š) with real numbers, expressions, and lists. The current
angle mode setting affects interpretation. For example,
mode returns
