5 digit decimal calculator is my worst problem. Can any one assist me understand it? I am a beginner at it. What book or other resource do you suggest for starting this subject?

Sounds like your bases are not strong. Excelling in 5 digit decimal calculator requires that your concepts be strong . I know students who actually start teaching juniors in their first year. Why don’t you try Algebrator? I am pretty sure, this program will aid you.

Greetings, I am in Algebra 2 and I bought Algebrator last month . It has been so much easier since then to do my math homework! My grades also got much better. In other words, Algebrator is splendid and this is exactly what you were looking for!
