jawab yang a pake cara minta tolong

sifat komutatif.

1. -36 + 50 = 50 + (-36) = 50 - 36 = 14
2. 124 + 137 = 137 + 124 = 261
3. 285 + (-171) = -171 + 285 = 285 - 171 = 114
4. 1.236 + 2.458 = 2.458 + 1.236 = 3.694
5. 38 × 34 = 34 × 38 = 1.292
6. 61 × (-40) = -40 × 61 = -2.440
7. 80 × (-57) = -57 × 80 = -4.560
8. -244 × (-81) = -81 × (-244) = 81 × 244 = 19.764

terimakasih. maaf klo ada yang salah soalnya matematika adalah kandang kecerobohan saya^_^
