Hello i would like to know what 1+1 is please and thank you

The answer to your question of 1+1 = 2

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

Iwould say false, not positive but if prices went up for both stores, technically there will be less buyers?
