While I am not Prof. Singh, I'll take a stab at answering this.
Assuming you're talking about Principia Mathematica, the goal of the text was not to prove that 1 + 1 = 2. It was actually an attempt to describe the set of rules from which all of mathematics could be derived from, and how to do so. This was proven impossible in later years, but the work was still very influential in philosophy, logic, and mathematics. 1 + 1 = 2 IS proven in the text, but only as a milestone towards the authors' larger goals.
