Question

Fill in the blanks to make the following statements true:
(i) (-5)+(-8)=(-8)+(___?____)

(ii) [13+(-12)]+(__?__=13+[(-12)+
(-7)]

(iii) (-4)+[15+(-3)]=[-4+15]+ __?__​

Answer 1

Step-by-step explanation:

(–5) + (– 8) = (– 8) + (-5)

–53 + 0 = –53

17 + (-17) = 0

[13 + (– 12)] + (-7) = 13 + [(–12) + (–7)]

(– 4) + [15 + (–3)] = [– 4 + 15] + (-3)

Answer 2

Answer:

i. ( -5) + ( -8) = ( -8 ) + ( -5 )

ii. [ 13 + ( -12 ) ] + ( - 7 ) = 13 + [ ( -12 ) + ( -7 ) ]

iii. ( -4 ) + [ 15 + ( -3 ) ] = [ -4 + 15 ] + ( -3 )
