How can you make 1000 by using sixteen 4's?

Answer 1

( 4 * 4 * 4 * 4 * 4 ) - { [ ( 4 + 4 + 4 ) / 4 ] * ( 4 + 4 ) } * [ ( 4 / 4 ) ^ 4 ] * ( 4 / 4 )

I figured it out by myself. Breakdown of brackets:

( 1024 ) - { 24 } = 1000 , the rest were simply multiplying by one.
* [ ( 4 / 4) ^ 4 ] = * [ 1 ^ 4] = * 1
* 4 / 4 = * 1

{ } are the outer-most brackets.
[ ] are the middle brackets.
( ) are the inner-most brackets.
* means multiply.
+ means add.
- means subtract.
/ means divide.
^ means to the power of ...
