Translation of Magenta

I try to learn English as much as possible so that I can travel next year to the United States. I would agree to your proposal but I also need to find good teachers. My goal is quality and speed.
Short question: when searching Spanish numbers, what would you write in Google? In Spanish, of course? In English I would write: 'spanish numbers' and not 'numbers in spanish'. The results are almost the same.
I can already speak a little English but not too well. So I'm more cautious about making mistakes. I want to improve my English, because it is also good for your confidence and communication skills.
