What is the solution for the determinant?

|1 7 |
|0 -3|

How do you find the solution? I'm probably going to feel really stupid because it's probably simple but I'm just having some problems. Okay, a lot.

you could do

(1*-3) - 7(0) = -3

in general though see:

To find the solution for the determinant of a matrix, you can follow these steps:

1. The determinant of a 2x2 matrix A = |a b|
|c d|
is calculated using the formula: det(A) = (a*d) - (b*c).

2. For the given matrix |1 7 |
|0 -3|
apply the formula: det(A) = (1 * -3) - (7 * 0).

3. Simplifying the expression, you get: det(A) = -3.

Therefore, the solution for the determinant is -3.

Don't worry if you find certain concepts challenging! Mathematics can be complex, and everyone learns at their own pace. It's important to keep practicing and seeking help when needed.
