Answer 2

Subtract: -)

(i) 7-(-20) = 7+20 = 27

(ii) (-14)-(-16) = -14+16 = 2

(iii) 500-(-453) = 500+453 = 47

(iv) 0-(-363) = 0+363 = 363

(v) (-1500)-(-1234) = -1500+1234 = -266

Evaluate: -)

(i) (-3)-(-7)+11 = -3+7+11 = -3+18 = 15

(ii) 27-(-19)+(-40) = 27+19-40 = 46-40 = 6

(iii) 15+(-19)-13-(-10) = 15-19-13+10 = 25-32 = -7

(iv) 25-[(-8)+(-2)] = 25-[-8-2] = 25-(-10) = 25+10 = 35

HOPE it helps to you!!!
