Can you be a bit more clear about when subtracting or adding two numbers in scientific notation, why do the exponets need to be the same? ? I may perhaps be able to help if I knew some more . A proper computer program can help you solve your problem instead of paying big bucks for a algebra tutor. I have tried many math program and guarantee that Algebrator is the best program that I have come across . This Algebrator will solve any algebra problem that you enter and it also clarifies every step of the – you can exactly reprint as your homework assignment. However, this Algebrator should also help you to learn algebra rather than only use it to copy answers.

Some professors really don’t know how to explain that well. Luckily, there are programs like Algebrator that makes a great substitute teacher for algebra subjects. It might even be better than a real professor because it’s more accurate and faster !

Wow, that's cool news ! I was so annoyed but now I am quite thrilled that I will be able to improve upon my grades! Thank you for the info guys! So then I just have to get the software and do my homework for tomorrow. Where can I find out more about it and purchase it?
