Apps That Act Like Math and Science Tutors for Homework Help

Sometimes when your kid needs help with homework, it's easy to lend a hand. Other times, not so much. When research or reading is involved, it might be a little easier to figure things out, but more advanced math and science -- especially if it's done differently than when we were in school -- can be tricky. If a live tutor is more of a commitment than you're looking for, consider trying one of the apps on this list to get your kid that extra assist on demand. Since some of these tools give up the answer to problems pretty easily, it's a good idea to supervise, to prevent copying and promote actual learning.
