25 plus 4 is 29: 25 + (1 = 26, 2 = 27, 3= 28, 4 = 29)
the answer is 24. what you can do is: 5+3=8 8+4=12 12+3=15 15+10=25 25-1=24
9 plus 16=25 3 squared is the same as 3 times three and 4 squared is the same as 4 times 4 3 times 3 + 4 times 4 9 plus 16 = 25

It is: 7+6+5+4+3 = 25
-4/25 + 19/25 = 15/25 = 3/5
25 + x
The answer is 25 but I do not know the rule. If someone else knows the rule feel free to edit my answer. first thing i would like to tell that their no particular rule to solve this problem. But if we consider the working of calculator then the addition will be done as follows. ((((((((1+2)+3)+4)+5)+4)+3)+2)+1) = 25 (((((((3+3)+4)+5)+4)+3)+2)+1) = 25 ((((((6+4)+5)+4)+3)+2)+1) = 25 (((((10+5)+4)+3)+2)+1) = 25 ((((15+4)+3)+2)+1) = 25 (((19+3)+2)+1) = 25 ((22+2)+1) = 25 (24+1) = 25 solve from innermost bracket towards outer This is just a consideration of calculator if you solve through calculator the producer will look as above. If any one knows any simple answer please feel free to continue this discussion.
