Answer 1

15) -25 + 10 = -15

16) 30 + (-14)

= 30 - 14

= 16

17) - 8 - 9

= -8 + (-9)

= -17

18) 23 + ... = 10

23 + y = 10

y = 10 - 23

y = -13

Jadi, angka yg tepat untuk mengisi titik2 tersebut adalah angka -13

19) -100 + n = -20

n = -20 + 100

n = 80

20) Suhu sekarang

= - 8 - 2

= - 8 + (-2)

= - 10

Answer 2

Penjelasan dengan langkah-langkah:

=> 14.)

0 + 10 - 9 = 1

A. Satu langkah ke selatan dari bendera ✔

=> 15

-25 + 10

= -15 (a) ✔

(-) + (+) = -

=> 16

30 + (-14) = 16 (d) ✔

(+) + (-) = -

=> 17

-8 - 10 = -18 (b) ✔

(-) - (+) = -

=> 18

n = 10 - 23

= -13 (c) ✔

=> 19

n = -20 - (-100)

= 80 (✔a)

(-) - (-) = +

=> 20

-8 + (-2) = -10 (c) ✔

(-) + (-) = (-)

=> 21

12 + 13 + (-35) = 25 + (-35)

= -10 (d) ✔

=> 22

10 - 8 + 3 = 5 m (c) ✔

=> 23

A = 2 - 4 = -2

A = -5 + 3 = -2

A = -2 (c) ✔

=> 24

A ke C = 8 + 9

= 17 km (b)

=> 25

10 - (-4) = 14 derajat (a)
