Need help in formula field in Salesforce?

Can someone help me create the following formula.
I have 2 conditions a custom number field should be 30 or less and the created date should be 14 days or older.

I have now:

A formula checkbox on Contact:

IF(Today()Account.CreatedDate >=14 && IF(Account.Total_Number__c <= 30), True, False)

getting Error: Syntax error. Missing ‘)’

I’m not a formula hero (yet) please advise me 😉
