8+1+5+5+3+8+10+30=70 The answer is 70
It is: -5+1+8+5 = 9
It is: -9+8+(-5)+3+1 = -2
1+1+1x1+5 =1+1+1+5=8
8 + 1 = 9 5 + 4 = 9 9 + 9 = 18 ( 8 + 1 + 5 + 4 = 18) The answer is 18.
1 plus 9, 2 plus 8, 3 plus 7, 4 plus 6, 5 plus 5, 6 plus 4, 7 plus 3, 8 plus 2, 9 plus 1, and 10 plus 0.

1 plus 2 plus 3 plus 4 plus 5 plus 6 plus 7 plus 8 times 9=100
9/8 = 1/2 + 5/8 as multiply 1/2 by 4 to make lower number the same, i.e. 1/2 = 4/8 then 4/8 + 5/8 = 9/8 which is 1 and 1/8
5/12 plus 1/8 = 13/24
5 + (10 x 2) + 8 ÷ 4 + 1 = 28
x - 8 + x - 5 + x + 1 = 3x - 12
