321 = (3 x 100) + (2 x 10) + (1 x 1)
The first step to writing a number in scientific notation is to divide that number by a power of 20 such that the greatest place value is the units. In this case, this can be done by dividing by 100: 321/100=3.21 This is the start of our answer. The second part is to express the number we divided by as its power of 10. 100 is the second power of ten, or 102, so we need to write this alongside the number as a multiplication. Thus, 321 in scientific notation is 3.21x102
321 tenths (321/10) as a decimal = 32.1
Note that 321 is the same as 321.0. From the starting point, which is between 1 and 0, move 2 decimal places to the left to get: 3.21 x 10² So that is the value in scientific notation.
300+20+1

0.321 is 321 thousandths or 321/1000
