If a is the opposite of 2 and B is one less than the reciprocal of a, then A-B is equal to asking the great God for help

If a is the opposite of 2 and B is one less than the reciprocal of a, then A-B is equal to asking the great God for help

a=-2,b=-1/2-1=-3/2,a-b=-2-(--3/2)=-2+3/2=-1/2.

Given that a and B are opposite to each other, C and D are reciprocal to each other, and B is not equal to 2 / 3, find the algebraic formula
The value of 3a-6b + 6 of 2CD + 3a,

If you know that a and B are opposite numbers, C and D are reciprocal numbers, and B ≠ 2 / 3, find the algebraic formula (3a-6b + 6) / (2CD + 3a) because a and B are opposite numbers, C and D are reciprocal numbers, so a = - B, CD = 1, so (3a-6b + 6) / (2CD + 3a) = (- 9b + 6) / (- 3B + 2) = (3 * (- 3B + 2)) / (-...)

If a and B are opposite to each other, C and D are reciprocal to each other, and the absolute value of E is 2, find the cubic value of a + B / E-CD + E

a. B is opposite to each other, a + B = 0
c. D is reciprocal, CD = 1
The absolute value of E is 2, e = 2 or - 2
Cube of a + B / E-CD + e
=0/e-1+e^3
=-1+e^3
(1) E = 2, the above formula = - 1 + 8 = 7
(2) E = - 2, the above formula - 1-8 = - 9
