Meaning of this anki sentences


#1

Why does this mean,
Why don’t I go - わたし が いきましょう
I read that いきましょう means let’s go. So this sentences I got from Anki but I didn’t make any sense for me, because I don’t see any ka particles and any negative verb. Can someone explain.

It’s not a translation that is strictly following the Japanese grammar, but it’s a natural English sentence that might be said in the same situation as the Japanese sentence.

If the looseness of the translation doesn’t fit your study intentions, you can just ignore it I suppose.
