1. The problem is to solve the numbers 12, 13, and 14. 2. Since these are individual numbers and not equations, we interpret the problem as finding their sum or analyzing them as a set. 3. To find the sum, use the formula for addition: $$\text{Sum} = 12 + 13 + 14$$ 4. Calculate the sum step-by-step: $$12 + 13 = 25$$ $$25 + 14 = 39$$ 5. Therefore, the sum of 12, 13, and 14 is $$39$$. 6. If the problem intended something else, please clarify, but based on the given input, the sum is the most straightforward solution.
