Time for MATH MINUTE! (provide your favorite theme music
here).
Get out
your paper & pencil, because I have a new puzzle for you!!
PUZZLE #85 Building numbers
A. How
many whole numbers can you build using only the numbers 1, 2, 3, and using only
the operations of addition, subtraction, multiplication, and division, if you
have to use ALL 3 and ONLY the 3 numbers 1, 2, 3 in each calculation?
For
example, you could multiply 1x2x3 = 6, or you could add 1+2+3 = 6, or do a
combination 1x(2+3) = 5, or ??
B. Same
as above, but using ALL 4 and ONLY all 4 numbers 1, 2, 3, 4.
We
know that there are at least as many as above since you can multiply each of
the numbers from part A. by 4, right?
Have
fun!
