0 times x is written as 0x. This is always equal to zero because anything times zero is always zero.
"< 0" For example x < 0 means "x less than zero".
3Y*12X = 0 is equivalent to YX = 0 In functional form, it is Y = z*(X = 0) where z can have any value. Here (X = 0) is 1 if X = 0 and the statement is TRUE 0 if X ≠ 0 and the statement is FALSE.

8 x 0 x 27 = 0
x
[0, x] assuming both 0 and x are included. If neither are included it would be (0, x). If 0 is included but x is not then it is [0, x). If x is included but 0 is not then it is (0, x].
6 x 0 x 5 = 0 Because any number multiplied by 0 is equal to zero, 6 x 0 = 0 and then 0 x 5 = 0.
