... 26.41 or 26.43. Again, realize that we never get an exact measurement. Even if the water level seemed to be right on the 26.4 graduation, we would report 26.40 mL, but we cannot report “exactly 26.4 mL.” Reporting “exactly 26.4 mL” implies 26.4 with an infinite number of zeros (26.400000000, etc.). ...

... In order to read numbers correctly, we need to know the order of each place value. The order is the following: 1,000,000 is one million 100,000 is one hundred thousand 10,000 is ten thousand 1,000 is one thousand 100 is one hundred 10 is ten 1 is one 0.1 is one tenth 0.01 is one hundredth 0.001 is o ...
