CPU & Memory How to add/multiply numbers with scientific notation (2.343e-5)

Hi,
I'm need to do some addition and multiplication of scientific nottaion numbers, in the form 34.23423e-10 for example.

I was echoing the list of numbers to stdout, then using bc -l, then I find that this does not seem to work for numbers with exponential notation. Could someone help me out here? I want to do somethng like 'a - b*3=?' Thanks!
