Every Saturday I’ll give you a couple of idioms to learn. An idiom is a saying or phrase whose meaning cannot be taken from the literal meanings of the words.
take stock: count the merchandise, supplies, etc. in stock. Also: take inventory.

calculated risk: some action that might fail, but you think it will succeed.
Example:
