4 + (14 - 2) = 4 + 14 - 2
A. 4 - (-14 - 2) = 4 + 14 + 2 ------------------------WRONG
B. (4 - 14 ) - 2 = 4 - 14 - 2 --------------------------WRONG
C. 4 - (-14) - (2) = 4 + 14 - 2 ------------------------RIGHT
D. 4 + 14 + (-2) = 4 + 14 - 2 ------------------------RIGHT
E. - (-4 - 14) - 2 = 4 + 14 - 2 ------------------------RIGHT
Answer: C, D and E.
