Multiplying And Dividing A Vector By A Number; Adding And Subtracting Vectors - HP -28S Manual

Key in the vector [2 3 4]. You can use either spaces or the non-radix
mark (the comma if you have selected the period as the radix mark) to
separate 2 from 3 and 3 from 4.

For multiplication, the order of the arguments makes no difference,
just as it makes no difference when you multiply two numbers. How-
ever, for division, the vector must be in level 2 and the number in
level 1.
Divide the vector by 5.

Adding and Subtracting Vectors
You can add and subtract vectors just as you add and subtract num-
bers, provided that the vectors have the same number of elements.
For subtraction, the order of the arguments is important, just as it's
important when you subtract one number from another.
For this example, subtract the vector [-10 20 30].
