6x6 devide by 5 and add 2
3 and 3/8

-1,-2,+2,-4,+4,-5,+5, +0. the sequence is subtract twice, add once, subtract again, add, then subtract, then add twice.
5/6 + 4/6= 9/6 which is also 1 1/2. You add 5+4 which would make it 9/6, 6 goes into 9 once leaving 3/6 which is 1/2, so 1 1/2.
6x6 devide by 5 and add 2
-- Throw away the 6 and the 2 . -- Add up what's left.
Multiply 6 by 5 = 30 Divide it by 2 = 15 Add the 9 = 24

6 + 6 + 6 + 6 + 5 =29.
5/6 + 4/6= 9/6 which is also 1 1/2. You add 5+4 which would make it 9/6, 6 goes into 9 once leaving 3/6 which is 1/2, so 1 1/2.
IT looks like the operations is "add 4 subtract 3, add 5 subtract 2, add 6...". So the next step would be to subtract one. That would make the next number 11.
8 plus 7 divided by 5 then add 6.
The lowest number you could add to make it divisible by 10, 2, and 5 would be 7. 23 + 7 = 30 30/10 = 3 30/2 = 15 30/5 = 6 Also, technically, you could add (-3) to make 20. 23 + (-3) = 20 20/10 = 2 20/2 = 10 20/5 = 4 Basically, you could add any number to 23 that would get a multiple of 10, since 2 and 5 are both factors of 10 to begin with.
