9x + 6 = 2 9x = -4 x = -4/9
It is: (9-4-2) times 8 = 24
9 / 4 converts to 2 and 1/4
Because multiplication is commutative.
5x = 5 times 9, 2y = 2 times 4 so 45 - 8 ie 37
9/8 ("9 over 8")
2/3 x 2/3 is 4/9

Yes. 2 x 2 x 3 x 3 = 4 x 9 = 36
2 1/2 x 4/9 = 1 1/9 or one and one ninth. Expressed as a decimal, this is equal to 1.1 recurring (that is, 1.1111...)
No, a negative number times a negative number will equal a positive answer. e.g. -2 x-2 = 4 (a positive 4) e.g. -3 x -3 = 9 (positive)
