## Operations with lists of numbers

To demonstrate operations with lists of numbers, we will create a couple of
other lists, besides list L1 created above: L2={-3,2,1,5}, L3={-6,5,3,1,0,3,-4},
L4={3,-2,1,5,3,2,1}. In ALG mode, the screen will look like this after entering
lists L2, L3, L4:
In RPN mode, the following screen shows the three lists and their names ready
to be stored. To store the lists in this case you need to press K three times.

### Changing sign

The sign-change key (\) , when applied to a list of numbers, will change

list, for example:
Subtraction of a single number from a list will subtract the same number from
each element in the list, for example:
