    Round Up

    NOT SURE. I THINK ADAMS WAY IS NOT VALID 2ND OPION

    ADAM HAS MADE UP HIS OWN METHOS OF ROUNDING. STARTING AT THE RIGHTMOST PLACE IN A DECIMAL NUMBER, HE KEEPS ROUNDING TO THE VALUE OF THE NEXT PLACE TO THE LEFT UNTIL HE REACHES THE PLACE TO WHICH THE DECIMAL NUMBER WAS TO BE ROUNDED. FOR EXAMPLE, ADAM WOULD USE THE FOLLOWING STEPS TO ROUND 11.3524 TO THE NEAREST TENTH:

    11.3524-11.352-11.35-11

    IS ADAMS METHOD A VALID WAY TO ROUND?

    THANK YOU

    Nope. It is not a good way to round. For example, look at the number 2.468. If you round to nearest integer (ones place) , doing each digit one by one you get 2.468\implies2.47\implies2.5\implies3, whereas if you use only the tenths digit you get 2.468\implies2
