That's good.
my $number = 0;

You shouldn't use my with "$_" and you should avoid using $_ in serious
programs as much as possible because it can get devastated too easily.
print "Enter number:";
An English typo "Enter number" should be "Enter a number".
chomp($number =<>);
if ( $number = /[0-9]/) {
This is wrong.
It is not "wrong", in the sense that the syntax is correct, it just does
something different than what the OP intended.
You should use "=~" (the pattern match operator)
m// is the pattern match operator, "m" stands for match. =~ is the
binding operator, it binds the left operand to the right operand.
