Standard form is of the form where and n is an integer. To do this you find a first and then n will be the number of decimal places to the left or right you have to go to reach the original number.

With 83,000 you get 8.3 as only that is between -10 and 10. To get 83,000 from 8.3 you'd move the decimal place4places right so you getn=4

If you have 0.957 then you'd get a =9.57 and n=-1 because the decimal moves one place to the left
