As a whole I am both
safe and secure.

Behead me and I become

the domain of beasts.

What am I?

What mathematical symbol can be put between 5 and 9, to get a number bigger than 5 and smaller than 9?

What has a ring but no finger?

Jenifer is learning to drive her car. She went down a one way lane and in the wrong direction. But she do not break any law.

I am thinking of a five-digit number such that:
The first and last digits are the same, their submission is an even number and multiplication is an odd number and is equal to the fourth number. Subtract five from it and we obtain the second number. Then divide into exact halves and we get the 3rd number.

What number I am thinking of?
