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:

Rate of Change. A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x x is the independent variable and y y is the dependent variable, then. rate of change = change in y change in x rate of change = change in y change in x. Rates of change can be positive or negative.

Writing {\displaystyle x\in A} x\in A means that "x is an element of A". Equivalent expressions are "x is a member of A", "x belongs to A", "x is in A" and "x lies in A". The expressions "A includes x" and "A contains x" are also used to mean set membership, however some authors use them to mean instead "x is a subset of A".
