<p>That should be quite a relief diddly!</p>

<p>Seed question was 19</p>

<p>Sent from my SCH-I535 using CC</p>

<p>tigerash, the question asked for the sum of the integers. {-4±2+0 = -6 }</p>

<p>-6 is less than 0 tigerash</p>

<p>No what was the context of the seed question?</p>

<p>Another question was when you a and b what combination gives the largest value?
I put B I forgot but some if the answe rs were a^2b or something g like that</p>

<p>Sent from my SCH-I535 using CC</p>

<p>it was a - b i think for that one</p>

<p>I think the seed asked for mode or something </p>

<p>ben 10 what were the restirctions { i.e. 0<A<1 }</p>

<p>Thekongo I think that’s what I got</p>

<p>dlee, the question had this t-chart where it listed the first digit one side of a 2-digit number and all of the numbers found with that digit on the other side.
Ie.
1-1,2,3,4,5
2-3,3,5,5,4
3-4,5,6,7,8
I cant remember specifically the numbers but the question said which amount of recorded seeds was most common. 19 was written like 4 times or something and was the most.
Poppers, from what I remember, the question asked what was the least-valued integer of three consecutive integers that equal 0.
I picked -4 then. (Im 90% that was what the question asked)</p>

<p>Oh yeah, the seed one was 19 thanks benh10</p>

<p>A>1 B<1 absolute of a = Absolute of b </p>

Yeah I thought the answer to the consecutive one was -4 cause I don’t remember it asking for the least sum</p>

<p>Definently a-b because a positive minus a negative is a positive</p>

<p>I picked b^2a.</p>

<p>Multiplied by 2, the power will always be even and so the negative value of b becomes positive. So, if you have like 2, (-2)^4 equals 32.
Thats greater than 2–2, 4.</p>

<p>2*-4=-8</p>

<p>dlee, Im now pretty sure it asked for the least-valued integer. Poppers, are you 100% sure it asked for the sum?</p>

<p>Working is correct about the one with the absolute values of a and b. b is negative but no matter what number that was put in for a when it was squared and multiplied by 2 it would always be positive and greater</p>
