Question

4.55 x 10^13= a
1.78 x 10^12= b
a - b = ?

Answer 1

what is a and what is b?

Answer 2

a is one order of magnitude higher than b, so to be able to do this calculation in your head just multiply 4.55 by 10 and subtract one from the exponent of 10, like so: 45.50*10^12

Answer 3

Now you can just subtract the 1.788 from 45.50 and keep 10^12 as is
