Math problem 4 +( 4+ 4)/( 4+ 4) =5 in the second grade of primary school.
In fact, a recursive computer is a disjoint calculation. Algorithm: The operations at the same level follow the order from left to right, and the operations at different levels follow the order of multiplication and division first and then addition and subtraction.
For example:
54+38-25
=92-25
=67
