Because work is the amount of energy transferred into or out of a system, not counting energy transferred by heat conduction.
The work done by a machine is the output energy provided by the machine in an intended task, while the work done on a machine is the input energy required to operate the machine. The work done by the machine should ideally be greater than the work done on the machine to ensure efficiency.
The machine has 250 J of work due to friction because the work done on the machine (300 J) is greater than the work output by the machine (50 J). This indicates that friction is opposing the motion of the machine and causing energy loss.
The output work from a machine cannot be greater than the input work because of the law of conservation of energy. Energy cannot be created or destroyed, only transformed from one form to another. Therefore, the output work of a machine cannot exceed the input work that was initially put into it.
well the advantage of that is pie, not math pie but pie that you eat
When the output force is greater than the input force on a simple machine, the machine provides a mechanical advantage, making it easier to perform work. This allows the machine to lift or move heavier loads than would be possible with just the input force alone.

The IMA of a machine is greater than 1 whenever the output force is greater than the input force.

-- The output work can't be greater than the output because they are, by definition of the terms, the self-same quantity, and consequently can be neither greater not lesser, but must at all times remain identical. -- The output work can't be greater than the INPUT ... unless additional energy is supplied inside the machine ... because total energy of a system is conserved, and cannot be created ex nihilo.
no
It sure can. A machine as simple as a lever can produce an output force that is greater than the input force. Perhaps you are confusing "force" with "energy"?
probably that less than greater than stuff, still cant figure out which one is less than and which one is greater than.
well the advantage of that is pie, not math pie but pie that you eat
It tells me that the machine is imaginary and does not exist.
Yes it Can because a negative number cant be greater than zero unless its an absoloute value.
