What is the opposite of the number -2 1/3

OpenStudy (unklerhaukus):

a number , plus its opposite , equals zero

OpenStudy (anonymous):

ooooohhh

OpenStudy (unklerhaukus):

so if the opposite number is denoted: \(x\) \[-2 \tfrac13+x=0\] to isolate \(x\) add the \(2\tfrac13\) to both sides of the equation

OpenStudy (anonymous):

ok so its just the opposite so it would be just 2 1/3

OpenStudy (anonymous):

OpenStudy (unklerhaukus):

yes that's right, other terms for the opposite are the 'negation' or the 'additive inverse'
