**Reiny**, Friday, October 9, 2009 at 9:02amIs there a type somewhere?

Usually we don't write leading zeroes of whole numbers like you did in 04980000007507

Furthermore, whether your number is a whole number or a decimal, the 7507 part at the end becomes rather "insignificant".

How many decimal places should your answer contain?

As to your question 10^4+10^4+10^3

we cannot add powers with different exponents.

In this case evaluate each one.

so

10^4+10^4+10^3

= 10000 + 10000 + 1000 = 21000

(certainly not 10^11, which would be

100000000000 )
