Properties of Real Numbers (Algebra 1.1)
1.
Which property is illustrated

Which property is illustrated
by the equation
ax + ay = a(x + y)
(A) distributive
(B) commutative
(C) identity
(D) associative
The distributive property of
multiplication over addition is
simply this:
It makes no difference whether
you add two or more terms
together first, and then multiply
the results by a factor,
a(x + y)
or whether you multiply each
term alone by the factor first,
and then add up the results,
ax + ay

Which statement best
illustrates the additive identity
property?
(A) 6 + (-6) = 0

2.
Which statement best
illustrates the additive identity
property?
The additive identity property
states that you can add 0 to any
number and it keeps its identity
– it stays the same.
(A) 6 + (-6) = 0
This is best illustrated by answer
(B), in which 0 is added to 6, and
the sum is (still) 6!
(B) 6 + 0 = 6
(C) 6(2) = 2(6)
(D) 6 + 2 = 2 + 6
