DS is stumbling on in class math tests, for instance he is flipping (+) and (-) sign and obviously not arriving at the right answers. Class test results are scattered and DS is frustratred.

Is there any AT device that can read a problem with exponents and parenthesis?

Would love to hear what others have found to work.

Happy Thanksgiving and TIA....
