Jawaban ada di bawah
1. 24 + 76 = 76 + 24 = 100
2. 35 + 47 = 68 + 14 = 82
3. (41 + 57) + 61 = 41 + ( 57 + 61) = 159
4. 62 + (41 + 28) = (62 + 41) + 28 = 131
5. (42 + 62) + 51 = 42 (62 + 51) = 155
6. 47 x 21 = 21 x 47 = 987
7. 48 x 26 = 26 x 48 = 1248
8. 21 x 43 = 43 x 21 = 903
9. (12 x 20) x 30 = 12 x (20 x 30) = 7200
10. 35 x (15 x 20) = (35 x 15) x 20 = 10500
semoga bermanfaat
