WebDistributive Law The "Distributive Law" is the BEST one of all, but needs careful attention. This is what it lets us do: 3 lots of (2+4) is the same as 3 lots of 2 plus 3 lots of 4 So, the 3× can be "distributed" across the 2+4, into 3×2 and 3×4 And we write it like this: a × (b + c) = a × b + a × c Try the calculations yourself: WebIt is possible, however, to add, subtract, multiply, and take powers of matrices with certain restrictions. It is also possible to find the inverse of some matrices. This topic introduces these concepts with 2×2 matrices before generalizing them for …

A necessary condition for two lines to intersect is that they are in the same plane—that is, are not skew lines. Satisfaction of this condition is equivalent to the tetrahedron with vertices at two of the points on one line and two of the points on the other line being degenerate in the sense of having zero volume. For the algebraic form of this condition, see Skew lines § Testing for skewness.
