it is peice of my mind
Positive acceleration = speeding up. Negative acceleration = slowing down.

Acceleration doesn't mean "speeding up". It only means that the speed or direction of motion, or both, are changing. Speeding up is positive acceleration in the direction you're moving. Slowing down is negative acceleration in the direction you're moving, or positive acceleration in the opposite direction.
Positive acceleration = speeding up. Negative acceleration = slowing down.
Positive is speeding up and negative is slowing down
Positive acceleration = speeding up. Negative acceleration = slowing down.
Positive acceleration ==> speeding up Negative acceleration ==> slowing down
Its slowing down (but still moving).
The car is slowing down
Acceleration is a change in velocity. Assuming a constant direction, if you're speeding up that is positive acceleration. If you are slowing down, that's negative acceleration. Either way you are accelerating.
Yes.If the car is backing up, but slowing down, then its velocity is in the negative direction, and its acceleration is in the positive direction.

If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.
de acceleration just means slowing down. Acceleration means speeding up. Actually any change in speed is considered to be acceleration. Slowing down is called negative acceleration or (de-acceration) and speeding up is called positive excelleration.
