25 The answer is 25
25+15=40+9=49
Yes and 9+16 = 25
1+9+25=35 not 41, this is a false statement
It is: (23+9) -25 = 7
16 + 9 = 25
79 49 + 25 = 74 74 - 4 = 70 70 + 9 = 79
6 + 5 + 3 + 2 + 9 = 25
1+3+5+7+9=25
25
90
So, laying out the question in traditional format: 2 + -25 + 22 + -9 = ? Starting from the left, 2 + -25 = -23 -23 + 22 = -1 -1 + -9 = -10 The solution is -10.
