Using Math Functions with Lists

Using Math Functions with Lists

When a math function (see Chapter 2: Math Operations) is

applied to a list, it is calculated for every element in the list.

Therefore, the function must be valid for every element in the

list.
You cannot perform a mathematical function on two lists of

different sizes. For example,

{1,2,3}+{4,5,6,7}

results in an error.

Mathematical rules always apply; for example,

1

P

{0,1,2}

results

in an error because 1 cannot be divided by 0.

Perform mathematical functions with
