The countdown is really a "checklist" that operates on a timeline that counts backwards to the precise time that spacecraft controllers want to launch their spacecraft. At every console is a book with all the procedures that must be followed, in their precise order, and everyone keeps track of the status of the launch by following along in their copy. A "check mark" is placed at every procedure when it's reported completed.

Because time is negative in their arbitrary coordinate system (chosen for convenience) during this period.

At exactly launch instant, time equals zero.
Just after launch, time is positive in their coordinate system.

When they say "t minus ten seconds", the mathematical statement they are saying is "t = - 10 sec".
