It´s like adding them. You pretend that the second number is a positive number and then you add the two numbers together. For example: (-7) - (-2) = -7 + 2 = -5 (-2) - (-7) = -2 + 7 = 5

nine add 7 to get from -7 to 0 then add 2 to get to 2 7 + 2 = 9

You have to multiply the bottom number by the whole number. then add it to the top number. EX: 1/2+3=7/2

2. 2 + 3 = 5 Or if you mean like add 3 to the prime number, then add that to the prime? 2 still works!! 2: 2 + 3 = 5. 5 + 2 = 7

The next number in the sequence is 9. The rule is to add 2, then subtract 1, add 2, subtract 1, and so on.

When you add zero to a number, the number does not change. Ex: 5+0=5 5+2+0=7

14

You add 7 -5 + 7 = 2

No, unless you add another odd number, for instance 2+3 is 5, but 2+3+7 is 12.

you need to add 7 1`s to get 7.

7

It is the number halfway between them or the number got when you add them and divide by 2. So for 7 and 10, the number 8.5 is the median.
