To be good in math...

These 3 qualities are a few of the most important in order to be good in math

1. Patience/ Perseverance

2. Don't be afraid to ask a lot of questions

3. Willingness to learn

I believe that if anyone has these three traits, they can become good in math; whether they are good at it to start with in the first place or not.
Patience is something that may be easy to obtain, but not easy to keep for long as math will always test your patience. Math isn't always easy, especially when learning new concepts or problem solving. With patience and perseverance you can keep on going, keep on solving these problems no matter how frustrating it gets or no matter how difficult it may become. Having the willingness to learn is also key.

Sometimes math will just make you so angry because you can't get it, or will make you just want to give up, so that's why you need to persevere and be willing to learn. Everyone's bound to make mistakes, but you just need to keep on trying! Keep on asking questions if you don't get something! Questions will always help you to grow in your knowledge and understanding, they will always benefit you!

These traits won't exactly make you smarter right away, or make you genius in that sense.. these characteristics will help you develop good math habits and therefore will help you in the long run to become good in math!
