Fill the Blanks
With the common mathematical operators +, -, *, / try to fill in the blanks in the equation below to make it work.
2 5 2 2 6 4 10 10 7=10
For an extra challenge, whatever operators you use in the first 4 spaces, you must use in the same order in the last 4 spaces.

you can also do it: 2-5-2-2+6+4+10-10+7
yep.. also
2-5+2+2+6-4-10+10+7
good puzzle.. but there's too many answers.. maybe saying you HAVE to use every symbol at least once would make it harder
2-5+2+2+6-4-10+10+7
good puzzle.. but there's too many answers.. maybe saying you HAVE to use every symbol at least once would make it harder
using every symbol, you can also do it
2*5*2*2+6+4+10+10/7=10
2*5*2*2+6+4+10+10/7=10
JMAN, you would not follow the order of operations. Parentehesis, exponents, multiplaction and division, and THEN addtion and subtraction.
I had (2*5*2*2+6+4+10+10)/7 = 10 after about ten seconds. It was probably ten minutes later before I found the given solution.
What's the point of a given solution when there are many answers? If the author of a teaser does not know the answer (or answers) the correct forum is "Teasers Without Answers".
