–500 + 300. (Points : 1) –800 200 800 –200

Youre adding to a negative number. So you just subtract again. -200

Think about it like this, if youre 15 underwater, and you "raise" or "add" 5 feet. You go towards the surface 5 more feet, so youre 10 feet under. Understand?

OpenStudy (raincloud):

-15 + 5 = 10

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

thx

OpenStudy (anonymous):

but the 10 still negative cause you're still underwater
