"< 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.
400,000 = (4 x 105) + (0 x 104) + (0 x 103) + (0 x 102) + (0 x 101) + (0 x 100)
1,000,000 = (1 x 1000000) + (0 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)
3,000 = (3 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)

To write 22,600,000 in expanded form using exponents, you would express it as 2.26 x 10^7. This is because 22,600,000 can be written as 2.26 multiplied by 10 raised to the power of 7. The exponent indicates how many times 10 is multiplied by itself, which in this case is 7 times.
[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.
800,000 = (8 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)
400,000 = (4 x 105) + (0 x 104) + (0 x 103) + (0 x 102) + (0 x 101) + (0 x 100)
0 Anything times 0 is 0
300,000 = (3 x 1000000) + (0 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)
1,000,000 = (1 x 1000000) + (0 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)
