... and a 0? Having used 10 digits (0 through 9) to count to 9, we make a new “tens place,” and assume that the digit in that position is the number of tens. For example, 57 is 5 tens and 7 ones. This saves us from needing a new digit for each number; we can stick to our original ten digits. When we get ...

UNIT EQUATION APPROACH TO PROBLEM SOLVING Conversion
... How did we know which of the two conversion factors to apply? If we look at the units, we started with cm and want to cancel then. Because anything over itself, including units, is equal to ! one and would cancel out of a factor, by putting cm in the denominator, cm would cancel out of the expressio ...
