You put that number with a little number over it depending on how many times that number is multiplied by itself.
The are used to represent numbers using powers of ten.
powers, or exponent
powers
If you mean the number of digits, this is roughly equivalent to the logarithm (base 10) of the number. However, it's a bit more tricky to find an exact expression. Rounding the logarithm up helps, but you will still be off by one, for exact powers of 10.
Spiderman's costumeb represents the super powers he was granted after being bitten by a spider. Also the costume represents his separate identity when he is using his super powers.
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
The form that uses only powers of ten are logarithms to base 10. The scientific notation does use powers of ten but the original number is also used in this representation.

Numbers expressed using exponents are called powers. When writing a number expressed as an exponent, the number is called the base. For example, in 23 two is the base.
