Explanation:  I pretty much drew out the problem to figure out how much wheat there would be at each time. So 1=1 2=3 3=7 4=15 and from there I realized the pattern was multiply by two and add 1 so the next would be 5=31 and then finally 6=63

About Me: I don't like math but I do it anyways

Explanation:  First, measure 1 kg of wheat. Then transfer the 1 kg to the other side with the weight. Doing this lets u weigh 2 kg of wheat. Then transfer and repeat so you can measure 4 kg. Then 8kg the 16 kg then 32kg and lastly 64kg. That gets 6 operations. But you have to find 63 so measure 1 kg and take that off. That makes 7 operations.
