Question

given that a=(-10),b=7 and c=(-3), verify that addition is communicative and associative. Also show that subtraction is neither communicative nor associative.​

Answer 1

Step-by-step explanation:

Given that

A= -10

B = 7

C = -3

Addition is commutative

A+B =B + A

-10 + 7= 7-10

-3 = -3

Addition in Association

(A+B )+C = A + (B+C)

(-10+7)-3 = -10+(7-3)

-3 -3 =-10+4

-6 = -6

Subtraction in commutative

A - B = B - A

-10-7 = 7 - (-10)

-17 = 7+10

-17 not equal to 17

Subtraction in Association

(A-B)-C = A - (B- C)

(-10-7)- -3 = -10-(7 - -3)

-17+3. = -10-(7+3)

-14 = -10-10

-14 = -20

,not equal
