1. The problem is to understand why subtracting $\pi$ from 2 is done or what it means. 2. Subtraction is a basic arithmetic operation where you take away one number from another. 3. Here, subtracting $\pi$ (approximately 3.14159) from 2 means calculating $2 - \pi$. 4. Since $\pi$ is about 3.14159, and 2 is less than $\pi$, the result will be negative. 5. Calculate the value: $$2 - \pi \approx 2 - 3.14159 = -1.14159$$ 6. This means if you start with 2 and take away $\pi$, you end up with approximately $-1.14159$. 7. This operation is straightforward subtraction, and the negative result indicates that $\pi$ is larger than 2.
