Help finding the determinant of a 4x4 matrix?

https://math.stackexchange.com/questions/1599082/help-finding-the-determinant-of-a-4x4-matrix

Here is how you should write it down in practice.

A = ⎝ ⎜ ⎜ ⎜ ⎛ 50 - 5 0 - 7 3 - 8 5 2000 2 - 4 3 - 6 ⎠ ⎟ ⎟ ⎟ ⎞

Correct notation for multiple intervals for a function's range

https://math.stackexchange.com/questions/2674059/correct-notation-for-multiple-intervals-for-a-functions-range

In your example

[[0, 5], (25, 100), (1000, 8000]]

, one way of writing this is

[0, 5] \cup (25, 100) \cup (1000, 8000] .

\cup

means union (of sets).

How many integers between [3,000, 8,000] have digit sum 20?

https://math.stackexchange.com/questions/339692/how-many-integers-between-3-000-8-000-have-digit-sum-20

Method 1: Using generating functions, you want the coefficient of

x^{20}

(x^{3} + x^{4} + \dots + x^{7}) (1 + x + \dots + x^{9})^{3} = \frac{x ^{3} ( 1 - x ^{5} ) ( 1 - x ^{10} ) ^{3}}{( 1 - x ) ^{4}}

Equivalently, we drop the

x^{3}
