Depends... what type of work?
If you mean, like, for example: -2
If you have -4 + -2, it would be negative 2, because if you have to add, and both signs are to the left of the x coordinate plain, you actually subtract.
Just learned that this year :p

When do you say that the work done is positive or negative?
There are different conventions as to what work is negative and what work is positive. The convention used by engineers and physicists is that work done BY the system on its surroundings is positive while work done ON the system by its surroundings is negative. Chemists reverse these conventions.
What is negative energy in physics?
what I mean is, the alcubierre drive needs negative energy to work so what are the properties of negative energy
When can work be negative physics?
If you apply force in the same direction an object moves, the work on the object is positive.If the force is in the opposite direction as the direction the object moves, the work on the object is negative.
What are examples of negative work?
Type your answer here..IF ANGLE BETWEEN FORCE AND DISPLACEMENT IS 180OR GREATER THAN 90 WORK IS NEGATIVE. I.E BODY THROW UPWARD
Is rolling a cart up a ramp an example of negative work?
"Negative work" is defined as energy exerted in the opposite direction from the displacement of the object. So here, in addition to adding to the gravitational potential energy, the work is positive.
Can work done by a force be negative?
Yes. If force is negative, then work will be negative.
When work is positive and when is negative?
when work is positive and when playing is negative
Can work positive or Negative in physics how?
Yes Work can be positive or Negative.

What are positive and negative work ethics?
what is positive and negative
What is the work of negative work?
maybe forcably work?
Should positive go to positive in a circuit?
No, this will not work. Postitive to Negative/Negative to Positive will work.
When negative work is being done what happens to potential energy?
Negative work increases potential energy.
What can be said about a situation in which work done is negative?
the formula F.S cos angle is used (the dot product) so if angle is 0,cos angle=1 hence work done is positive and maximum if angle is 90 so cos 90 is 0 hence work done is minimum if work done is negative the angle is 180 The work done by friction is always negative (opposite the force) Since work is force x displacement, a negative value for work could mean that the displacent was negative
