Before solving this problem,just think simple arithmatical question of this type.What number would you subtract from 10 to get 6.How do you do it?10-6? Same thing is to be done hee also.kkkSubtract a+19 from a-31\n(a-31)-(a+19)\n=a-31-a-19\n=-50 and that is your answer

I depends on what the last # is if it continues as a 1 then the answer is 3

14+r-1+6=56\n19+r=56            <-------Combine like terms\n19+r-19=56-19      <-------Subtract 19 from both sides to get r by itslef\nr=37

a + 18 > -3\na + 18 - 18 > -3 - 18 (Subtracting 18 from both sides)\na > -21\na= ] -21 , inf [

19 + 7 = 26\n26 + 5 = 31\n31 + 3 = 34\n34 + 1 = 35\n35 + (-1) = 34

well, you look at the biggest digit, not including the sign.  lets say it is -7-5.  7 would be the biggest.  Then, see if its subtract or add.  This is add.  It has to be negative, since its a -7.  Another example is 7-9.  9 is the biggest, and since its a negative, the answer is a negative. One last one.  -2+9.  9 is the biggest, and since its possitive, the answer is positive.

adding two positive integers you just add like normal number\nand the same thing with subtracting two negetive integers except u add a - sign. then with adding one positive and one negetive u subtract the two numbers and whichever number is bigger u would add negetive or positive to the answer\nex. -9+4=\n9-4=5\n9 is the bigger number\nso ur answer is -5\n\nsubtracting integer u keep the first number, do the opposite sign, the last number u switch, like if ur last number is a negetive then u wiould change it to a positive and visa versa\nex. 7-(-2)=\nleave the 7\nswitch the minus to a plus +\nchange the negitive 2 to a positive 2\nso it would be 7+2=9

You are very close. If K = -0.032 is accurate enough, then use it.\n\npA = Ae^(19 * -0.032)\np = e^(19 * -0.032) ~ 0.544\n\nIf you leave K = ln(.5)/22 then\np ~ 0.5496

If you add up all the letters in his name (A=1, B=2, etc) you get 169. And if you turn the 9 upside down you get another six. and if you add 500 to that you get 666, so I think you might be on to something.

-12.4 = -19.1 + n/-7.9\nThis can also be written as:\n-19.1 + n/-7.9 = -12.4\nn/-7.9 = 19.1 - 12.4\nn/-7.9 = 6.7\nn = (6.7)(-7.9)\nn = -52.93

guess if algebra, it would go like this 2 minus make a plus \nso 14- - (+) 14=28/14= 2

Adding a negative number is the same thing as subtracting a positive number. Picture a number line. +2 means to move right 2 spaces. -4 means to move left 4 spaces. You end up on the left side 2 spaces from 0. This is -2.
