If only 1 operation is happening, always go from left to right. it does matter with subtraction.

6 if order doesn't matter

There are: 8C6 = 8!/6!(8-6)! = (8 x 7)/(2 x 1) = 28.

Because if you rotate it about its center it looks different (not symmetric) no matter what the angle is.

There are infinitely many rational numbers between any two (different) numbers, no matter how close together they are.

it doesnt matter some might love it some might like it it doesnt matter

There is no commutative property in subtraction or division because the order of the numbers cannot be change. This means that when multiplying or adding it does not matter the order of the numbers because the answer comes out the same.

it doesnt matter

Because it doesn't matter what numbers you select to start the tree. If you do it correctly, the bottom branch will always have the same numbers.
