since you are adding I would start by assuming that the answer is going to be higher than the largest number on the list. the numbers are in a circle and the is one + and the rest are - the numbers are 1-8 and the sum of the difference are the same 2+6=8-1=7-3=4-5=
1+2=3
6-3=3
7-4=3
8-5=3
1+2=6-3=7-4=8-5=
Since each digit has 4 possibilities to be arranged, and 2 of the digits have the same value of 3, the number of arrangements would be 12. 4!/2! = 4 x 3 x 2!/2! = 12

You need two numbers to specify each point.To actually calculate the slope, divide (difference in y-coordinates) by (difference in x-coordinates).If you mean: (-1, 2) and (4, 3) then it is 1/5
Four ways:1 row with 6 in each row.2 rows with 3 in each row.3 rows with 2 in each row.6 rows with 1 in each row.
Exponential and logarithmic functions are different in so far as each is interchangeable with the other depending on how the numbers in a problem are expressed. It is simple to translate exponential equations into logarithmic functions with the aid of certain principles.
You cannot. The sum and difference cannot be the same for any pair of non-zero numbers.
On a five point star
use compatible numbers to estimate each difference 84-36
It is 21 and 9. Because you halve 30 to get 15, then add 6 to each to get the difference.

It is the table of contents
Since their difference is zero, they're the same number.Since they're the same number, each one is 1/2 of 150.Both numbers are 75 .
