Answer:
1: 1
2: 22
Explanation:
1 ) -5 + (-1) is -6, because they both have the same sign.
-6+7} when there is a negative and a postive, put the postive in front
so it will look like this 7-6 which is 1
2) 19+(-3) is basically 19-3, which is 16, and 16+6=22
Extra note:
when you see n+(-n), always remove the + sign and subtract
when you see -n+n, always switch the roles of the two
when you see -n+-n, remove the - sign and add it back later
when you see -n-n, think of -n+n
I hope these helps :)
