Standard form is a way to write very big or small numbers using times of 10^.
Method:
? = add 9 zeros behind the digit 2 = 2000000000 ← This is positive indices The other one is negative indices:
? = move the decimal point 9 times to the left = 0.000000002 If the number is a single digit, then in standard form it will not be a decimal. But for multiple digits, it have to be a decimal.
Example:
