Question

6. If a= 2,b= -1, c= -1 verify the
following properties:
a. a + b = b + a
b. a + (b + c) = (a + b)+c
c. a-b is not = to
d. a × (bx c) = (a xb)xc
e. a × (b-c) = (a x b)-(a x c)
f. a-(- c) is not equal to (a - b) -c
g. a ×(b + c) = (a × b) + (a ×c)
h. a ÷ (b + c) = (a + b) ÷ c
i. axb= b xa
j. a = b is not equal to b ÷a
