Explanation:
First solve 2+(4+8)
Always solve what is in the bracket first.
2+(12) = 14
Next solve each of the options to find out which one gives you the same answer as the question.
For A:
2+(6+8)
= 2+14
= 16 (X)
For B:
(2+4)+8
= 6+8
= 14 (✓)
For C:
(6+4)+8
= 10+8
= 18 (X)
For D:
(2+2)+8
= 4+8
= 12 (X)
Hence, B is the answer.
