There is a complement that when added equals one but you may be thinking of multiplying. A number times its reciprocal (multiplicative inverse) is equal to one. A number added to its additive inverse (opposite) is equal to zero.
Yes.

1 plus 1 equals 2 because 1 plus 1 is also actually 1 lot of 1 plus another lot of 1, which means when they are added, it will add to 2. 1 multiplied by 1 is actually 1 lot of 1, so one lot of 1 is still 1.
How about: 2 plus 5 equals 7 as one example

This one's a little confusing, but 54, 18, 6 and 2 are all factors of 108 that when added total 80.

Another one of its factors magically appears.
1 plus 1 equals 2 because 1 plus 1 is also actually 1 lot of 1 plus another lot of 1, which means when they are added, it will add to 2. 1 multiplied by 1 is actually 1 lot of 1, so one lot of 1 is still 1.

1 and 159, when added together, is one possible answer.
One-third (1/3) and one-quarter (1/4) can be added together by finding a common denominator. The least common multiple of 3 and 4 is 12. Therefore, 1/3 equals 4/12 and 1/4 equals 3/12, so when added together, 1/3 + 1/4 equals 7/12.
Factors of 59 are itself and one because it is a prime number.
