1. The problem is to evaluate the expression $+1$ raised to the power of 3. 2. We write the expression as $$+1^3$$. 3. Raising a number to a power means multiplying the number by itself as many times as the exponent indicates. 4. So, $$+1^3 = +1 \times +1 \times +1$$. 5. Multiplying these together, we get $$+1 \times +1 = +1$$ and then $$+1 \times +1 = +1$$. 6. Therefore, $$+1^3 = +1$$. 7. The final answer is $$1$$.
