Time for MATH MINUTE! (provide your favorite theme
music here).
Get
out your paper & pencil because I have a new puzzle for you!!
PUZZLE #12 And the sum of the numbers is? Dec. 4
– Dec. 8
Lets have a contest.
I will tell you the difference
between 2 whole numbers and the product of the 2 numbers. Then you must tell me
the sum of the 2 numbers without first finding them?
Speed counts (so I use a
calculator).
For example, suppose the
difference of the numbers is 6 and their product is 91. What is the sum of the
numbers?
(Hint: if you need help, see below)
Now test your method on
these sets:
difference = 2 and product = 48
difference = 5 and product = 84
difference = 5 and product = 336
BONUS Puzzle: Find the
numbers and explain why the method in the hint below works?
(Hint: square 6 and add 4 times 91 to get
information about the sum of the 2 numbers)
