That one was incorrect, but don't feel bad.  Borrowing with zeros is tough.  The correct answer is 3,719.

I recommend reading Volume 1 of the Learn Math Fast System.  That book will quickly teach you how to add, subtract, multiply and divide numbers in your head.  Plus, you'll learn a lot of cool tricks that make math easier to solve.  Don't worry about going back to volume 1, older students can complete it in about a month.  Younger students will need more time, but whatever age you are, you'll become a math whiz after reading that book.
