1.

(i) 15 + (−8) = 7

(i) 15 + (−8) = 7(ii) (−16) + 9 = −7

(i) 15 + (−8) = 7(ii) (−16) + 9 = −7(iii) (−7) + (−23) = −30

(i) 15 + (−8) = 7(ii) (−16) + 9 = −7(iii) (−7) + (−23) = −30(iv) (−32) + 47 = 15

(i) 15 + (−8) = 7(ii) (−16) + 9 = −7(iii) (−7) + (−23) = −30(iv) (−32) + 47 = 15(v) 53 + (−26) = 27

2.

(i) 153 + (−302) = −149

(i) 153 + (−302) = −149(ii) 1005 + (−277) = 728

(i) 153 + (−302) = −149(ii) 1005 + (−277) = 728(iii) (−2035) + 297 = −1738

(i) 153 + (−302) = −149(ii) 1005 + (−277) = 728(iii) (−2035) + 297 = −1738(iv) (−489) + (−324) = −813

(i) 153 + (−302) = −149(ii) 1005 + (−277) = 728(iii) (−2035) + 297 = −1738(iv) (−489) + (−324) = −813(v) (−1000) + 438 = −562
