Răspuns :

1. (89+11)÷(99-89)÷(28÷7×3÷6+8)×(5×8÷10÷2)×5= 10

2. (63-7×7+16)÷(2×4×9-6×6-26)× 100×10-2090= 910

Sper că te-am ajutat! Spor la lecţii! :)

Răspuns:

100 ÷ 10 ÷ ( 4 × 3 ÷ 6 + 8 ) × ( 40 ÷ 10 ÷ 2 ) × 5 = ( 63 - 49 + 16 ) ÷ ( 8 × 9 - 36 - 26 ) × 1000 - 2090 =

10 ÷ ( 12 ÷ 6 + 8 ) × ( 4 ÷ 2 ) × 5 = ( 14 + 16 ) ÷ ( 72 - 36 - 26 ) × 1000 - 2090 =

10 ÷ ( 2 + 8 ) × 2 × 5 = 30 ÷ ( 36 - 26 ) × 1000 - 2090 =

10 ÷ 10 × 2 × 5 = 30 ÷ 10 × 1000 - 2090 =

1 × 2 × 5 = 3 × 1000 - 2090 =

2 × 5 = 3000 - 2090
