8) B, C
9) B
10) A, B, C
1) C; The communitive property does not apply to subtraction.
2) A; 2 + 4 * 3 = 14 does NOT EQUAL 3 + 4 * 2 = 12. The order of the numbers changes the results
3) C; The communitive property does not apply to division.
4) B; The communitive property does not apply to subtraction.
5) C; x * y + z = xy + z does NOT EQUAL x * z + y = xz + y. The order of the variables changes the results
6) C; The communitive property does not apply to division.
