Both these answers are missing the whole truth.
Acceleration is a vector quantity, so it has a magnitude and a direction. The sign of a vector quantity indicates the direction that the vector is pointing.
Acceration = dV/dT or change in velocity/change in time
Positive acceleration means that the change in velocity over change in time is positive, so the object is accelerating away from you with an increasing velocity or the object is coming towards you and it's slowing down.
Negative acceleration is the opposite. Either it's moving away and the change in velocity over change in time is negative (e.g. it's slowing down) or it's change in velocity over change in time is positive but it is accelerating toward you.

RE:
What is the difference between positive and negative acceleration?

Acceleration is the rate at which velocity increases while velocity is just your speed ex: the cars acceleration is 2 m/s/s while the the velocity is 4 m/s that means in a second the car's velocity will be 6 m/s because of its acceleration of 2/s/s

Positive acceleration is acceleration like everyone understands it to be.
Negative acceleration is deceleration but scientists just don't use that term.

Positive acceleration is going faster. Negative acceleration is going slower.
