Given that a and B are opposite to each other, and C and D are reciprocal to each other, find the value of 4 / 3 (a + B + 2) - 2CD

Given that a and B are opposite to each other, and C and D are reciprocal to each other, find the value of 4 / 3 (a + B + 2) - 2CD

Because a and B are opposite numbers, a + B = 0
Because C and D are reciprocal, CD = 1
That's fine
4/3(a+b+2)-2cd
=4/3×2-2×1
=Two thirds
