THE DISTRIBUTIVE PROPERTY
OF MULTIPLICATION
ANSWERS
THE DISTRIBUTIVE PROPERTY OF MULTIPLICATION ALLOWS US TO DISTRIBUTE OR GIVE MULTIPLICATION TO ADDITION OR
SUBTRACTION. IT MAKES NUMBERS EASIER TO WORK WITH AND ALLOWS US TO BREAK VARIABLES AND NUMBERS INTO PARTS.
4 x 72
4 x 72 CAN BE CHANGED TO
4 x (70 + 2), BECAUSE 72 = (70 + 2).
4 x 72 = 4 x (70 + 2)
4 x (70 + 2)
4 x (70 + 2)
BY CHANGING THE 72
TO (70 + 2) WE CAN
SOLVE THIS PROBLEM
IN OUR HEAD.
(4 x 70) + (4 x 2)
USING THE DISTRIBUTIVE
PROPERTY WE CAN SEPARATE
THE 70 AND 2 AND MULTIPLY.
(280) + (8) = 288
NOW THE MULTIPLICATION
IS EASIER AND CAN BE
DONE IN OUR HEAD.
280 + 8 = 288, SO 4 x 72 = 288.
SEE HOW WE DISTRIBUTE
THE 4 TO THE 70 AND 2?
Now you turn. Use the Distributive Property to solve the problems below.
