Get some graph paper, draw two axes and bisect them with a 45 degree sloping line. Next pick any point on that 45 degree sloping line and from that point draw a line parallel to the horizontal axis so that it intersects the vertical axis. Do the same thing from the point drawing a line parallel with the vertical axis so that it intersects the horizontal axis. These two lines represent represent the components of your vector and if you measure them they will be of equal length and thus of equal magnitude. For ANY angle of slope (other than 45 degrees) the two vectors will not be of equal length.
Assuming a full factorial design, it's the product of the levels over all independent variables. For example, in a two-factor design, in which each factor is considered at each of three levels, the so-called 23 design, the total number of conditions is 23 = 8. In a two-factor design in which one factor is considered at two levels and the other at three the total number of conditions is 2 ( 3 ) = 6.

When combining (adding) two negatives you get a negative. When multiplying two negatives you will get a positive.
Two coordinates define a point. You need two pairs of two coordinates to define two points and, therefore, a slope.

The adding of this two sound will give you total sound level of 87 dBSPL. Scroll down to related links and look at "Adding acoustic levels of sound sources - Combining decibels, adding of levels, or combining levels".
An inclined plane with one sloping side is called a ramp, used to move objects up or down with less force. An inclined plane with two sloping sides is called a wedge, used for splitting objects or holding them in place.
