Question

Please some one help me with this i don't know how to do these three problems

Answer 1

1)can't see the illustration 
2) -2+10=8  and-4+12=8
3) 123-180= -57  185-255=-70
Bart has -57 points and Sam has -70 points  which means that  Bart won the game because after adding up the sums  their games Bart has a total of -57 and Sam has a total of -70  and -57 is higher then -70.
