Violating Fundamental Maths Law

Some people are trying to violate the most fundamental maths law in this planet. Here, this is what I meant:

E.g.:
Situation 1
A says: I hate you! (-)
After some persuasion by B…
A says: Ok la, lets be friends! (+)
And they lived happily ever after (+)
(-) + (+) = +

Situation 2
BFF: During semester 1, I flirt a lot! I didn’t attend class la, hand up assignments late la…(-)
BFF: But I still study a bit. (+)
BFF: Then at last, I still in the Dean’s List what! (in a proudly manner) (+)
(-) + (+) = +
