The expression "beat your brains out" means to work very, very hard to try and figure something out or solve a problem, but with no success. It is used when someone is trying really hard to understand or do something, but they just can't seem to do it. For example, "I've been beating my brains out trying to understand math, but it just doesn't make sense to me." It is important to note that this is not a literal expression and should not be taken literally.
