Two of the following numbers add up to seventeen: 6 - 13 - 2 - 12 - 7 - 14

To find out which two numbers from the given options add up to seventeen, you can try adding each pair of numbers together and see if any pair yields seventeen.

Let's go through each pair:
6 + (-13) = -7
6 + (-2) = 4
6 + (-12) = -6
6 + (-7) = -1
6 + (-14) = -8

(-13) + (-2) = -15
(-13) + (-12) = -25
(-13) + (-7) = -20
(-13) + (-14) = -27

(-2) + (-12) = -14
(-2) + (-7) = -9
(-2) + (-14) = -16

(-12) + (-7) = -19
(-12) + (-14) = -26

(-7) + (-14) = -21

From the calculations above, we can see that none of the pairs of numbers from the given options add up to seventeen. Therefore, there are no two numbers from the given options that sum up to seventeen.

Are all of them negative numbers except for the 6?
