It follows directly from the definition of what 1, 2, and "plus" are. 1 and 2 are simply symbols that are associated with a particular quantity. For example, 1 ampersand is: &. 2 ampersands are: &&. 3 ampersands are &&&.
Addition can be defined by taking two sets, combining them into one set, and counting the number of things in the set. So If we take a set of ampersands that has 1 ampersand (&) and another that has 1 ampersand (&), combine those sets of ampersands into a single set (&&) and count the number of ampersands in it, then we have proved that 1 + 1 = 2.

What is 1 23 plus 1 23 plus 2 27?
To calculate 1 23 plus 1 23 plus 2 27, first convert the mixed numbers to improper fractions or decimal values. Adding them together: 1 23 + 1 23 = 2 46, and then adding 2 27 gives you 2 46 + 2 27. This results in 4 73, or if you simplify further, you can express it as 5 1 (if you convert 73 into a mixed number).
