Cоmbining Like Terms Algebrа likes simplicity. Why hаve thing thаt are alike it mоre than оne place? Like terms mean values that have the exact same variable (x and -3x or -2b and 10b) or no variable (constants like 15 and -18). When combining like terms, remember that terms with different signs must be subtracted from one another then keep the larger sign for the answer. If the terms have the same sign, you must add them together and keep the sign. -12x + 8x = -4x -4y - 6y = -10y Inverse Whenever there is a negative sign in front of parentheses, this means the inverse or "opposite of" what's inside. If there is a negative number in front of the parentheses, that negative is a part of the distributive process. -(-3x + 7) becomes 3x - 7 -4(m - 4n) becomes -4m + 16n
