Explicație pas cu pas:

4 + 4 × [ 4 + 4 × ( 4 + h : 4 ) + 4 ] : 4 = 52

4 × [ 4 + 4 × ( 4 + h : 4 ) + 4 ] : 4 = 52 - 4

4 × [ 4 + 4 × ( 4 + h : 4 ) + 4 ] = 48 x 4

4 × [ 4 + 4 × ( 4 + h : 4 ) + 4 ] = 192

4 + 4 × ( 4 + h : 4 ) + 4 = 192 : 4

4 + 4 × ( 4 + h : 4 ) + 4 = 48

4 × ( 4 + h : 4 ) = 48 - 4 - 4 → aplic metoda mersului invers

4 × ( 4 + h : 4 ) = 40

4 + h : 4 = 40 : 4

4 + h : 4 = 10

h : 4 = 10 - 4

h : 4 = 6

h = 6 x 4

h = 24 → numarul
