Question

27+(43+(−49))=(27+43)+(−49) type of property

Answer 1

Answer:

Associative property of addition

Step-by-step explanation:

Note:

Associative property of addition says

• a+(b+c) = (a+b)+c

27+(43+(−49))=(27+43)+(−49)

27+(43-49) = 70+(-49)

27+(-6) = 70-49

27-6 = 70-49

21 = 21

verified

Answer 2

Answer:

This is the example of associative property.

Step-by-step explanation:

Since, Associative property= a+(b+c)=(a+b)+c

therefore,

27+(43+(−49))=(27+43)+(−49)

27+(43-6)=70-49

27+(-6)=21

27-6=21

21=21

LHS=RHS

Hence proved!
