What is B + 2/3 solve

B + 2/3 is not a question, and doesn't look for an answer.

It's an expression that stands for a number. In order to know what number,

you need to know the value of 'B'. But then, if 'B' changes, the value of the

expression also changes. Immediately. Faster than the speed of light.

Possibly ... B + (2/3)

set it equal to 0

B + (2/3) = 0

- (2/3) - (2/3)

B = - (2/3)

I think that's what u had to do
