nope its -80
Change -65 - 15
Into -65+ (-15)
See? Stay, Change, Change
Keep the first number, change the operation symbol and change the second number from positive to negative or negative to positive.(Flip the signs).
Example: $-65 in your bank account PLUS another $-15= $-80
Even if the second number was positive, it would still be like this: $-65 MINUS +15 dollars= -80 because you took away 15 dollars. Get It? I hope so. No thanks needed, i am happy helping you and making you happy. Chat me or comment on my profile for more questions.
