B. 12 − 52 = (−40)

C. [(−15) + (−22)] + 35 = (−22) + [35 + (−15)]

D. (−68) + 68 = 0​

Answer 1

Answer:

A. commutative(a+b)=(b+a)

B. closure

C.assosiative(a+b)+c=a+(b+c)

D. additive inverse or additive identity (a number subtracted or added to itself gives 0)

Answer 2

Formula

a+b=b+a

c c

B.IDENTITY PROPERTY

A+B=C
