Question

12+3-15÷÷(-2-1)+30-64÷8-2+10-72÷(-8) (5-3)×[(-6)÷(5+1)-(-5)]-[(5+6)-(-7+9)-(-2)] [(-6+8)-(-15)÷3]×{-8-[-2+(8+2)÷(-3-2)]+(-4+8-5)}

Answer 1

Explicación 19 - 5 × 3 + 12 × 2 - 1

19-15 +24 -1=27

6 + 4 × 3 - 16 ÷ 8 + 3 × 2

6 + (4 × 3) - (16 ÷ 8) + (3 × 2)

6+12 - 2 +6 =22

4 - 10 ÷ 5 + 20 ÷ 2

4 - (10 ÷ 5 )+( 20 ÷ 2)

4- 2 +10 = 12

14 ÷ 7 × 2 + 9 × 3 ÷ 27 - 1

14 ÷ (7 × 2 )+( 9 × 3) ÷ 27 - 1

(14÷14)+(27÷27 ) -1

1+1-1 =1

64 ÷ 8 - 72 ÷ 12 + 3 × 4

(64 ÷ 8) - (72 ÷ 12) + (3 × 4)

8  -6+12 =14

50 ÷ 2 + 7 × 3 - 12 × 1

(50 ÷ 2) +( 7 × 3) - (12 × 1)

25 +21 -12 =34

65 × 4 - 15 × 2 + 40

(65 × 4) - (15 × 2) + 40

260-30+40 = 270

37 + 45 × 2 - 116 + 13

37 +( 45 × 2) - 116 + 13

37+90-116+13=24

35 - 8 - 2 × 1 + 5 × 4 - 12 ÷ 6

35 - 8 - (2 × 1 )+( 5 × 4) - (12 ÷ 6)

35 -8 -2 +20 -2 =43
