Homework Statement


Add (9.8x10^3s)+(9.9x10^4s)+(0.017x10^6s)

Homework Equations


None



The Attempt at a Solution


I have entered 125800, as well as 1.26x10^5 but the website marked both of those wrong. I've done this problem every way you could do it I think and it comes out to the same answer but the program won't accept it.

I presume this has to do with significant digits a.k.a significant figures.

(9.8x103s) + (9.9x104s) + (0.017x106s) = (0.98x104s) + (9.9x104s) + (1.7x104s)

So I worked out your problem also and it gave me 125800 and it just says add, but I'm guessing it doesn't want the answer but what you gave instead. Ugh I hate mastering physics... :(

You were already pointed to significant figures. Both numbers you have tried have too many.
