If a divides b and b divides a then either a is equal to b or a is equal to -b.
Additional note:
if a divides b, there exist a p such that ap=b.
and if b divides a, there exist a q such that a=bq.
then ap=(bq)p=b
=> b(1-pq)=0
=> pq=1 since b!=0
=> p=q=1 or p=q=-1
=> a=b or a=-b

Math words that stat with a B?
Bisector means a line that divides another lines in two equal halves.
If a divides b which one is the denomitor?
If a divides b then a is a factor of b and b is a multiple of a.Either of them could be the denominator. In a/b, b is the denominator while in b/a, a is the denominator.------------------------------------------------------------------------------------------------------------------If a divides b then b=n*a for some number n. Thus n=b/a
If a is equal to b. is not a equal to not b?
No because if a=4 and b=4 then a=b and not a can equal 6 and not b can equal 5 so ~a is not = to ~b
