Not unles you have a calculator. To add by hand, you need to convert to a common exponent, which is pretty straightforward
YES
They don't. They use bankerific notification, which involves imaginary numbers and allows fluid conversion of assets for fraudulent resale.
If you can subtract whole numbers you can subtract decimals. Forget about the decimal for a sec and subtract the numbers as if they were whole numbers. 2.5 -1.4 =1.1 hope this helps and if not yahoo usually has good examples.
As far as it is possible to tell, neither of the two are in scientific notation.
you subtract by lining your numbers and start from the ones place and continue going to the left
YES
You subtract the exponent of the divisor from that of the dividend.

It is not possible to answer this question because it is based on a false premise that you have to round off numbers.
Make them into improper fractions, find the least common denominator, convert them, subtract, reduce if possible.
That isn't possible.
30 and 1 is one possible pair.
If you can subtract whole numbers you can subtract decimals. Forget about the decimal for a sec and subtract the numbers as if they were whole numbers. 2.5 -1.4 =1.1 hope this helps and if not yahoo usually has good examples.
Subtract the subtrahend from the minuend to get the difference.
