8/9
The prime factors of 28 are 2 and 7. Their sum is 9.
-2 + -3 + -4 = -9
sum involves addition so the sum of 2 and 9 equals 2+9=11
8. To find 'the sum of' something, is just to add them together really. Eg - The sum of 9 + 3 = 12.
-23 is the sum of -32 and 9
the sum is the answer to an addition problem e.g.4+5=9 9 is the sum
2 + 9 = 11
9
The quotient of 18 and 2 is 9 The sum of 22 and 9 is 31 31-9=22
9 and 13. I divided by two and went +2 and -2
The probability is 8/36 or 2/9
