Nope, that sounds GT to me.
I think ND 3yos are not yet counting reliably with 1-to-1 correspondence, at least not all the way to 10. (In other words, they might have the numbers memorized, but they don't realize that each object corresponds to a number.) Adding and subtracting are beyond them.
The addition and subtraction (especially the subtraction) and the tangrams are the most telling points for me, particularly if she initiates these interactions. The more it's coming from her, the more GT she probably is. (For example, DS7 always drove the train and he's clearly HG+, but we have to ask DS4 for most things because he doesn't intiate school-y conversations as often. Granted, if he's GT, it's more creativity-based than DS7's. But I still don't feel comfortable calling him GT because he's just not as motivated to learn as DS7 was.)
How GT your DD is, I wouldn't hazard a guess. It's a bit early to tell. But especially if she initiates the math talk a lot, I'd feel pretty confident about saying that she's some level of GT.
