Question 209194
This sounds like fun!  Get as many different combinations as you can think of, and see which ones are missing.  Here are a that I could think of:


77/7-7=4
(7-7)/7 +7 = 7
((7*7+7)/7  =8
(7+7)/7 +7 =9
(77-7)/7 =10
(77+7)/7 =12
(7*7)/7+7=14  

77/7+7=18
 7+7+7+7 =28
7*7 +7/7 = 50
77-7/7 = 76
77+7/7=78
77+7+7=91

This sounds like a good group project or a contest to see who can come up with the most different numbers.  Am I right??


Have fun with the rest of these!!
