Arithmetic operators of the Perl operator: + (add),-(minus), * (multiply), / (divide), * * (power),% (remainder),-(monocular negative)

(1) the cardinality of power cannot be negative, such as (- 5) * * 2.5#error

(2) the result of power cannot exceed the limit expressed by computer, such as 10**999999#error.

(3) if the Operand of the remainder is not an integer, it is rounded to an integer; the right side of the operator cannot be zero.

(4) monocular negativity can be used as a variable:-$y * is equivalent to $y y *

(5) should be + =,-=, * =, / =, * * =,% =
