AN elevator began on the 4th floor of a building. From there the elevator traveled 8 floors up then 3 floors down then 4 floors down then 1 floor up. On what floor did the elevator stop?

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
