Question

Evaluate r + s for the given values
1) r= 7 , s= -21
2) r= -23 , s= -12
3) r= 32 , s= -24
4) r= -13 , s= -12
5) r= 35 , s= -15
6) r= -31 , s= 31

Answer 1

1) 7+-21=14
2) -23+-12=-35
3) 32+-12=20
4) -13+-12=-25
5) 35+-15=20
6) -31+31=0

Before asking, why didn't you use calculator to solve this all? What you had to do is just to put the numbers into r+s and calculate.
