Explicación paso a paso:

te paso la primera foto xq lo demas me da flojera

VERTICALES:

$1. \: \: 15 - 4 \times 3 + 7$

= 15 - 12 + 7

= 10

$2. \: \: \frac{8}{2} + {6}^{2} - \sqrt{121}$

= 4 + 36 - 11

= 29

$3. \: \: {5}^{3} - (3 + 7 \times4 - 1) - 9 \times 5$

= 125 - (3 + 28 - 1) - 45

= 125 - 30 - 45

= 50

$4. \: \: 2horizontal \: - 9$

= 2(25) - 9

= 41

$5. \: \: 4(3vertical) \: + {10}^{2}$

= 4(50) + 100

= 200 + 100

= 300

$6. \: \: \frac{4horizontal}{2}$

= 4(190)/2

= 760/2

= 380

$7. \: \: 6vertical - \frac{(4 - 3 \times {5}^{0} + 17 )}{3} + 12$

= 380 - {(4 - 3 + 17)}/3 + 12

= 380 - 6 + 12

= 386

$10. \: \: \frac{4horizontal + {4}^{2}}{5}$

= {4(190) + 16}/5

= 776/5

= 155.2

$11. \: \: \frac{2(5horizontal)}{3}$

= {2(36)}/3

= 72/3

= 24

...…..………………………………………………………………………………………………………………………………………

HORIZONTALES:

$1. \: \: \sqrt{ {9}^{2} + 7 \times {3}^{2} }$

= √81 + 63

= √144

= 12

$2. \: \: ({4 + 5 \times 2 - 9})^{2}$

= (4 + 10 - 9)²

= (5)²

= 25

$4. \: \: (4 \times {3}^{2} - \frac{12}{3} + 7 \times 9) \times 2$

= (36 - 4 + 63) x2

= (95)x2

= 190

$5. \: \: triple \: de \: 1horizontal$

= 3(12)

= 36

$7. \: \: doble \: de \: 7 \times 5$

= 2(7x5)

= 2(35)

= 70

$8. \: \: \frac{1horizontal}{4}$

= 12/4

= 3

$9. \: \: \frac{(1348 - 2 \times {5}^{2} )}{2} + 7 \times 8$

= {(1348 - 50)}/2 + 56

= 649 + 56

= 705

$12. \: \: \frac{7}{11} \: de \: 7vertical$

= 7/11 x 386

= 245.6
