What standard form means

Decimal point movement diagram showing 6.38 moving 3 places right to make 6380 and 2 places left to make 0.0638, with the rule a x 10^n where 1 <= a < 10

Standard form is built from powers of 10. Multiplying by $10^n$ moves the decimal point right if $n$ is positive and left if $n$ is negative.
