ても~なくてもwhether or not
Do it or don't: it makes no difference. The verb comes twice, first with ても and then with なくても, and after it comes what holds either way.
Whether he comes or not, we will start the meeting at nine.
How to form it
Verb 〜ても + the same verb 〜なくても
行っても行かなくても, 見ても見なくても. A する verb usually says its noun once: 予約してもしなくても. ある gives あってもなくても.
- After it
- What holds either way: 同じだ, 変わらない, いい, かまわない, or a plan or a rule that stands.
- Where you'll meet it
- Everyday talk, and wherever rules and prices are explained: notices, instructions, counters.

Two things to know
It isn't かどうか
English "whether or not" does two jobs. When you don't know which way it will go, it is かどうか. When it makes no difference which way it goes, it is ても~なくても.
I don't know yet whether it will rain or not.
You don't know which.
Whether it rains or not, the match will go ahead as scheduled.
It makes no difference which.
Words with an opposite: 勝っても負けても
When a word has a ready opposite, the second half is usually that, not the negative: 高くても安くても (expensive or cheap), 勝っても負けても (win or lose).
Win or lose, let's give it everything to the end.
