Math problem 7+6=( )+( )=( )+( )= ()?
It's too simple. 7+6=( 10)+(3 )=(5 )+(8 )=( 13 )

()+() As long as the sum of the two numbers in brackets is equal to 7+6 (that is, equal to 13), it can be filled in any way.

For example, 7+6 can be = (1)+(12) = (3)+(10) = (13).

= (4)+(9) = (2)+(11) = (13) and so on.
