Because both are characterised by their magnitude AND their direction.
it depends on the method of subtraction. If the vectors are drawn graphically then you must add the negative of the second vector (same magnitude, different direction) tail to tip with the first vector. If the drawing is to scale, then the resultant vector is the difference. If you are subtracting two vectors <x1, y1> - <x2, y2> then you can subtract them component by component just like scalars. The same rules apply to 3-dimensional vectors
3D shapes are three dimensional, just like 2D shapes are two dimensional.
The magnitude of the resultant of two like parallel forces is the sum of the magnitudes of the forces and its direction will be same as the direction of the parallel forces.
Well two dimensional means a flat shape, like a square, or a circle. A three dimensional shape means you can hold it, like the 3-D version of a square is a cube, and a 3-D circle is a sphere.
Like with all other right triangles, use the Pythagorean Theorem. If you have 2 vectors that form a right triangle, the resultant should be the hypotenuse. So you just need to square both of the vectors, add them together, then take the square root. a2+b2=c2
The poles are force vectors and vectors forces repel when they are opposed (in opposite direction).
Forces are vectors and, like all vectors, they have magnitude and direction. Forces can be added together using vector addition and to do so, it is necessary to know their directions.

added together, always ad vectors! Im assuming your working with vectors so "add them head to tail like elephants walk in the jungle"-Mr. Katramadakis (best teacher ever)
Perhaps you care to elaborate...if not, then ask yourself: Why do Frenchmen behave like Frenchmen Why do Germans behave like Germans Why do Gambians behave like Gambians Why do Norwegians behave like Norwegians Why do Nepalese behave like Nepalese Why do Venezuelans behave like Venezuelans. Get the point?
Dynamic dimensional constraints look like dimensions, but behave in the opposite way. Dimensions are driven by objects in change dimensional constraints drive and determine the lengths, radial sizes, and angles of objects. They also control the distances or points between objects.
The Big Bang Theory promotes the concept of the singularity as the origin of all fundamental forces (i.e., the gravitational, electromagnetic, strong and weak forces). The Big Bang singularity represents a true one dimensional consideration maintains that all the physical manifestations of our fourth dimensional reality, like the fundamental forces or primary interactions of the physics (i.e., gravitational, electromagnetic, strong and weak) and the individual attributes of Space and Time itself, were all defined within a one dimensional SpaceTime continuum. From our fourth dimensional subsistence, it is difficult to imagine other varying dimensional states, or transitions from these states.
they behave like idiots
They behave like very fierce and very angry.
ducks behave like kid
They behave like any animals.
Because scalars do not take in the direction but just the magnitude while vectors can. You can add vectors ONLY if they are in the same direction.
