Salut,
a = 7 + [ 7 + 77 ÷ 7 × (7 + 7) - 77 ÷ 7 ] ÷ 7
a = 7 + (7 + 77 ÷ 7 × 14 - 77 ÷ 7) ÷ 7
a = 7 + (7 + 11 × 14 - 77 ÷ 7) ÷ 7
a = 7 + (7 + 154 - 77 ÷ 7) ÷ 7
a = 7 + (7 + 154 - 11) ÷ 7
a = 7 + (161 - 11) ÷ 7
a = 7 + 150 ÷ 7
a = 7 + [tex] \frac{150}{7} [/tex]
a = [tex] \frac{199}{7} [/tex] ✔
a = 7 + { 7 + 77 : 7 × ( 7 + 7 ) - 77 : 7 } : 7
a = 7 + ( 7 + 11 × 14 - 11 ) : 7
a = 7 + ( 7 + 154 - 11 ) : 7
a = 7 + ( 161 - 11 ) : 7
a = 7 + 150 : 7
a = 7 / 1 + 150 / 7
a = 49 / 7 + 150 / 7
a = 199 / 7
a = 7 + ( 7 + 11 × 14 - 11 ) : 7
a = 7 + ( 7 + 154 - 11 ) : 7
a = 7 + ( 161 - 11 ) : 7
a = 7 + 150 : 7
a = 7 / 1 + 150 / 7
a = 49 / 7 + 150 / 7
a = 199 / 7
