5 + 6 + 4 = 15.
4 + 6 - 15 = -5
10+9+15+8+4+6+11=63
15
15 + 3 - (6 x 4) = -6
72
4 plus 5 plus 6 plus 7 plus 8 equals 30. To find the total, you simply add the numbers together: 4 + 5 = 9, 9 + 6 = 15, 15 + 7 = 22, and 22 + 8 = 30.
-3 + -7 + 5 + -4 + -6 = -15
The answer is 3/8 plus 6/4 = 15/8
x/6+4=15-4 -4x/6=11*6 *6x=66

The answer is: 25
