Question

Calculează respectând ordinea efectuării operațiilor

(69+3):3+8x4x0

135+75:25-(90-30):30

550:10:11x(48:3-24-12)

2x [307- 84:(9-5)]-3​

Answer 1

Răspuns:

Explicație pas cu pas:

1. 69+3=72  2. 72:3=24  3.8x4x0=0  4.24+0=24

1.90-30=60 , 2. 60:30=2, 3. 75:25=3, 4. 135+3=138, 5. 138-2=136

1. 48:3=16, 2.16-24= -8, 3. -8 -12= -20, 4. 550:10=55, 5. 55:11=5, 6. -20x5=  -100.

1. 9-5=4, 2. 84:4=21, 3. 307- 21=286, 4. 2x286= 572, 5. 572-3=569

Answer 2

Răspuns:

69 + 3 = 71

71 : 3 = 23 r 2

8 × 4 × 0 = 0

23 r 2 + 0 = 23 r 2
