(5*10^-5)+(2.46*10^-3)
------------
The exponents have to match to combine them.
Change either of both so they match.
---
5*10^-5 + 2.46*10^-3 = 5*10^-5 + 246*10^-5
= 251*10^-5
Then adjust the decimal point.
= 2.51*10^-3
======================
Or,
5*10^-5 + 2.46*10^-3 = 0.05e-3 + 2.46e-3
= 2.51e-3
Or 2.51*10^-3
---------------
e format, 2.46e-3 is less typing, and is commonly used.
