Could playing a musical instrument make you better at math?

Let's put it this way. The psychologists say there's all kinds of good stuff you get from learning to play an instrument. There's nothing bad comes from it unless it's something like becoming a rock star and ending up choking to death on your own vomit (or anybody else's vomit for that matter).

Some people think it's good for math too. Who cares? Go for it!

If it doesn't work for your math, there are books that help with this - Math Doesn't Suck by Danica McKellar, Cliffs Algebra I and other course guides, How to Double Your Child's Grades by Eugene Schwartz.

Used course guides are cheap. Buy a few. Use the best one for explanations and the rest for practicing with problems.

The only way to get good math scores is practice, practice, practice!

This is not problem-solving in the usual sense of the word. It's going through routines that you've memorized.

If you don't have a routine, improvise. This works with word problems. There's only so much info the teacher can hide in a word problem. If you just play around with the numbers and find a new number, that's probably the answer.

nop … but playing musical instrument can allow one's mind to be more receptive to stimuli.
