Vocaloid · Answer

I'll be honest, I've never learned the term "addition form" specifically but my best guess would be to just to add the inverse of 4.2 to -17.9

Vocaloid · Answer

so A - B = A + (-B)
-17.9 - 4.2 = -17.9 + (-4.2) maybe?

Allison · Answer

Omg. I meant "rewrite the expression using addition".

Vocaloid · Answer
