8x²y³ + 3x²y³ - x²y³ =
11x²y³ - x²y³ 10x²y³
===============================================
4ab - 6ab - 8ab + 3ab =
4ab + 3ab - 6ab - 8ab =
7ab - 14ab = - 7ab
================================================
4x²y - 3x²y + 8xy² - 5xy² =
x²y + 3xy²
11x²y³ - x²y³ 10x²y³
===============================================
4ab - 6ab - 8ab + 3ab =
4ab + 3ab - 6ab - 8ab =
7ab - 14ab = - 7ab
================================================
4x²y - 3x²y + 8xy² - 5xy² =
x²y + 3xy²
