Adding the opposite of a number is the same as subtracting the number. so 2 + (-1) = 2 - 1 = 1

15. kugler97

so a negative plus a positive in parethesis would give you either a negative or positive just type it into a calculator

16. omgitsmona

exactly! 2 + (-1) = 2-1 = 1 @skullpatrol

@aylin123 Do you understand that adding the opposite of a number is the same as subtracting the number. so 2 + (-1) = 2 - 1 = 1
