As is known, A. Einstein's key method was unification through symmetry. He was able to formulate a symmetry unifying space and time. He was also able to formulate a generalized symmetry describing acceleration and gravity. However, Einstein's third approach to creating a great unifying theory was unsuccessful because he lacked a symmetry that would unify gravity and light. He even wrote: "I am sure that in order to make real progress, it is necessary to elicit from nature one more some general principle". This paper attempts to prove that this general principle is the principles of algebra and arithmetic.
