2 cubed = 2*2*2 =8. 8+8+8= 24
-8 plus 15 = 7
2/3 + 2/8 is a problem involving making the denominators equal. Because a common multiple of 3 and 8 is 24, We'll use that. 16/24 + 6/24 = 22/24 You can then reduce 22/24 to 11/12. 11 over 12 is your answer.
1/12 + 1/8 = 2/24 + 3/24 = 5/24
2/3 plus 3/8 is equal to 25/24.
-1/3 + (-3/8) = -8/24 - 9/24 = -17/24.

2 + 655631 + (-5478) + (-24) + 8 = 650139
2 cubed = 2*2*2 =8. 8+8+8= 24
24
9/24 + 12/24 + 8/24 = 29/24 or 1 and 5/24
This website doesn't reproduce plus signs, so I'll assume that's what goes between those numbers. -16 + 24 = 8 -4 + 6 = 2
(2/3) + (7/8) = (16/24) + (21/24) = (37/24) = 1 and 13/24
12/36 + 8/24 = 2/3
8 5/6= 8 1/6
It is: x^2 +11x +24 = (x+8)(x+3) when factored
