WebSubtraction as the addition of the opposite. Another way scalar multiplication relates to addition and subtraction is by thinking about \bold A-\bold B A −B as \bold A+ (-\bold B) A+(−B), which is in turn the same as \bold A+ (-1)\cdot\bold B A +(−1)⋅B. This is similar to how we can think about subtraction of two real numbers!
