1. Let's start with a simple problem: What is $2 + 3$? 2. The problem is to add two numbers: 2 and 3. 3. The formula for addition is $a + b = c$, where $a$ and $b$ are numbers, and $c$ is their sum. 4. Here, $a = 2$ and $b = 3$, so we calculate $2 + 3$. 5. Adding 2 and 3 means counting 2 objects and then counting 3 more objects, which gives us 5 objects in total. 6. So, $2 + 3 = 5$. 7. The answer is 5!
