Solved, made a silly mistake. Thanks for reading.

The "mod 2 degree" of a mapping refers to the number of times a point on the target space is covered by the mapping. It is essentially a measure of how many times the mapping wraps around the target space.
The mod 2 degree is calculated by counting the number of times the mapping wraps around the target space in a given direction. This can be visualized by drawing a line from the starting point to the end point of the mapping and counting the number of times the line crosses the target space.
No, the mod 2 degree is always a non-negative integer. This is because it represents the number of times the mapping wraps around the target space, which cannot be negative.
The mod 2 degree is closely related to the concept of homotopy in topology. It is used to classify mappings between topological spaces, and can provide information about the connectedness and continuity of a mapping.
The mod 2 degree is an important tool in understanding the properties of mappings between spaces. It can help in determining if a mapping is surjective, injective, or bijective, and can also provide insights into the topological properties of the spaces involved.
