Distributive Property
The Distributive Property of multiplication
is the property that states that multiplying
a sum by a number is the same as
multiplying each addend by the number
and then adding the products. The
Distributive Property says that if a, b and c
are real numbers,
then a(b + c) = (a x b) + (a x c)
Addend
• An Addend is a number that is added to
another number.
• 2 + 3
=
5
Real Numbers
• Real Numbers are all irrational and rational
numbers. Real numbers are the Umbrella that
other numbers fall inside of.
Irrational Numbers
• Any real number that is not a rational number
and not an imaginary number. An example of
an irrational number is the square root of 2
because it cannot be written as a ratio of two
integers. Pi is also an irrational number.
Rational Numbers
• Rational Numbers are numbers that can be
written as a ratio of two integers. A fraction
containing a numerator and denominator that
are integers. Every integer is a rational
number. It comes from the word ratio.
Examples of Distributive property
36 + 8 = 44
Step 1
Step 2
Answer
4 (9 + 2) =
(4 x 9) + (4 x 2) =
36
+
8 = 44
Practice
1) 7 (8 + 3)
2) 3 ( 6 + 9)
Are these equal?
3) 55 + 10 =
11 (5
+ 0) =
4) 27 + 3 =
9 (3
+ 1) =
