A = %28matrix%282%2C2%2C5%2C1%2C3%2C2%29%29, B = %28matrix%282%2C2%2C-1%2C3%2C4%2C1%29%29
A - 2B = %28matrix%282%2C2%2C5%2C1%2C3%2C2%29%29 - 2%28matrix%282%2C2%2C-1%2C3%2C4%2C1%29%29 =
%28matrix%282%2C2%2C5%2C1%2C3%2C2%29%29 - %28matrix%282%2C2%2C-2%2C6%2C8%2C2%29%29 =
%28matrix%282%2C2%2C%285-%28-2%29%29%2C%281-6%29%2C%283-8%29%2C%282-2%29%29%29 =
