What about numbers that are very small? How can they benefit from being written in standard form? Let's try 0·092. We need to move the 9 and the 2 two places to the left (so we have a number more than 1 but less than 10). We indicate that the number needs to be divided by 10 twice using a negative power: 9·2 × 10^{2} Now try the example 0·00000864. The numbers 8, 6 and 4 (we always ignore 0's) need moving 6 places to the left: 8·64 × 10^{6}
