Question 1030413
 the sum of what integer and 181 is equal to -236 
n + 181 = -236
subtract 181 from both sides
:
n  = -236 - 181
Remember the law of signs, when the signs are the same, you add them
n = -238 - 181 = -417
then going back to the original equation n = -417, we have
-417 + 181 = -236, 
(the signs are different so we substract, the solution takes the sign of the larger number)
