### 5.38.7 The + operator applied on sequences

The infixed operator +, with two sequences as argument,
returns the total sum of the elements of the two sequences.

Note the difference with the lists, where
the term by term sums of the elements of the two lists would
be returned.

Input :

(1,2,3,4,5,6)+(4,3,5)

or :

’+’((1,2,3,4,5,6),(4,3,5))

Output :

33

But input :

[1,2,3,4,5,6]+[4,3,5]

Output :

[5,5,8,4,5,6]

Warning

When the operator + is prefixed, it has to be quoted (’+’).
