## Explanation

**Addition theorem**: In mathematics, an addition theorem is a formula such as that for the exponential function e = e·e that expresses, for a particular function f, f in terms of f and f. Slightly more generally, as is the case with the trigonometric functions sin and cos, several functions may be involved; this is more apparent than real, in that case, since there cos is an algebraic function of sin.

* The homotopy addition theorem is a formula relating the element j*.(x) with the
elements 3% = tr.:(x0), x1, ..., x, 1. It will be used in the proof of the Hurewicz
theorem, and it appears implicitly in obstruction theory in the fact that the
obstruction ...
