The solution to the expression $1 + 1$ is quite straightforward:

$1 + 1 = 2$

Would you like more practice with basic operations or help with other types of problems? Here are some related questions for you:

1. What is $3 + 4$?
2. What is $5 - 2$?
3. What is $6 \times 2$?
4. What is $8 \div 4$?
5. What is the sum of $10 + 15$?

Tip: When solving simple arithmetic problems, always remember to perform addition and subtraction from left to right, and multiplication and division in the order they appear from left to right as well.
