This anwser using AI, please

a) 133 + (−10) = 123; 133 + (−10) = 123. Vậy, 133 + (−10) = 133 + (−10). Kết quả là =.

b) (−120) + 7 = −113; (−120)(−120) = 14400. 14400 > −113. Kết quả là <.

c) (−110) + (−3) = −113; (−110)(−110) = 12100. 12100 > −113. Kết quả là <.

d) (−133) + 133 = 0; (−133) + 133 = 0. Vậy, (−133) + 133 = (−133) + 133. Kết quả là =.

e) 120 + (−120) = 0; 120 + (−120) = 0. Vậy, 120 + (−120) = 120 + (−120). Kết quả là =.
