sebutkan operasi bilangan bulat. Minimal 10 jawaban.

- komuntatif
3 + 5 = 8. 5 + 3 = 8
10 × 500 = 5.000. 500 × 10 = 5.000
7 + 3 = 10 3 + 7 = 10
100 + 400 = 500. 400 + 100 = 500
5 × 6 = 30 6 × 5 = 30
8 + 2 = 10. 2 + 8 = 10
6 × 10 = 60. 10 × 6 = 60
90 × 10 = 900. 10 × 90 = 900
50 + 30 = 80. 30 + 50 = 80
66 + 34 = 100. 34 + 66 = 100

1.

238 + 50 + 12
= 288 + 12
= 300

————————————————
2.

130
89
——— (+)
= 219

3.

15 x 16 x 4
= 240 x 4
= 960

————————————————
4. Sifat distributif

(514 x 42) + (514 x 24) + (514 x 34)
= 514(42 + 24 + 34)
= 514(100)
= 51400

————————————————
5.

5 + 3 x 10 : 2
= 5 + 30 : 2
= 5 + 15
= 20

————————————————
6.

(-2) x (-5) : 2 - 10
= 10 : 2 - 10
= 5 - 10
= -5

————————————————
7. Sifat distrobutif

2 x (-2) + 100 x (-2)
= (-2) [(-2) + 100]
= (-2) [98]
= -196

————————————————
8. Sifat Asosiatif

(10 + 98) + 2
= 10 + (98 + 2)
= 10 + 100
= 110

————————————————
9. Sifat Asosiatif

(20 + 48) + 2
= 20 + (48 + 2)
= 20 + 50
= 70

————————————————
10.

2 x 3 + (-2) : (-2)
= 6 + 1
= 7
