Unless

UNLESS

Unless means the same as if...not. Like if, unless is followed by a present tense, a past tense, or a past perfect tense (never by a conditional). Unless is used instead of if...not in conditional sentences of all types. The order of the clauses doesn't matter with sentences using unless.

(Edufind.com, n.d.)

Unless = except if, only if and if not.

The club is for members only.

You can´t go in unless you are a member.

You can´t go in except if you are a member.

PROVIDED (THAT) AND PROVIDING (THAT)

Provided and providing these expressions mean IF or CONDITION THAT is the same that AS LONG AS for example:

(Speakspeak, n.d.)

No need for that

The word THAT can be omitted for example:

Unless, as long as and provided or providing can be at the beginning or at the middle but when we use at the beginning we must use comma.
