WebExample. The matrix = [] is skew-symmetric because = [] =. Properties. Throughout, we assume that all matrix entries belong to a field whose characteristic is not equal to 2. That is, we assume that 1 + 1 ≠ 0, where 1 denotes the multiplicative identity and 0 the additive identity of the given field.If the characteristic of the field is 2, then a skew-symmetric … 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!
