Finding limits can be fun! Here’s a simple way to handle different problems:

1. Direct Substitution: Just put the number in the equation! If you get a regular number, that’s your limit. For instance, if you want to find $\lim_{x \to 2} (3x + 1)$, you get $7$!

2. Factoring: If putting in the number gives you something like $\frac{0}{0}$, try factoring. This means you will change the expression into a simpler form first.

3. Rationalization: If you have square roots in your problem, you can multiply by the conjugate to get rid of the square root.

4. Infinity Situations: When $x$ goes to $\infty$ (a really big number), look at the main parts of the expression to understand how it behaves.

Practice these steps, and you'll get the hang of limits in no time! Keep up the great work! 🎉
