Is there a shortcut for this sum?

5.25x10^5 + 6.37x10^6

If it was 5.25x10^5 TIMES 6.37x10^6 I could rearrange it to;

5.25x6.37x10^5x10^6

And then add the powers;

5.25x6.37x10^5+^6

To give;

33.4425x10^11=3.34425x10^12

But it’s PLUS not TIMES

Can we manipulate the powers when it’s PLUS?

Or (ignoring using a calculator) do we have to do it the long way;

5.25x10^5=525,000
6.37x10^6=6,370,000
And then add the two.

?

Re: Is there a shortcut for this sum?

Cant we add like:
525*10^3+637*10^4

10^3(525+6370)

10^3*6895

6.895*10^6

Or simply take 10^6 common if youre comfortable with decimals. It's the easiest I can do.
