15+5x{20-5:[2-15:(18-15:5)]x4:15}+15=
15+5x[20-5:(2-15:15)x4:15]+15=
15+5x(20-5:1x4:15)+15=
15+5x12+15=90
Nu stiu daca calcularile sunt corecte, le mai poti calcula o data.

15+5X{20-5:[2-15:(18-15:5)]X4+15}X4+15=
15=5X{20-5:[2-15:(18-3)]X4+15}=
15+5X[20-5:(2-15:15)X4+15]+15=
15=5X(20-5:1X4+15)+15=
15+5X(20-5X4+15)+15=
15+5X(20-20+15)+15=
15+5X15+15=30+75=105
