...These tools allow you to connect different datasets and distill thousands of rows into a few meaningful numbers.
1. VLOOKUP and HLOOKUP -These functions search for a value in one column (or row) and return a corresponding value from another. * VLOOKUP (Vertical): Searches for data in columns. * Syntax: =VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup]) * Logic: "Find this ID in this table, and give me the value from the 3rd column." * HLOOKUP (Horizontal): Searches for data in rows.

3. Matrices (Question 6a)
Verify that A \cdot (\text{adj } A) = (\text{adj } A) \cdot A = |A| \cdot I_3 for A = \begin{bmatrix} 2 & 3 & 4 \\ 3 & 0 & 1 \\ 2 & 1 & 5 \end{bmatrix}.
* Find the determinant |A|:
* * Find the Adjoint (\text{adj } A): This involves finding the cofactor of each element and then transposing the resulting matrix.
* Cofactors: C_{11}=-1, C_{12}=-13, C_{13}=3, C_{21}=-11, C_{22}=2, C_{23}=4, C_{31}=3, C_{32}=10, C_{33}=-9
* * Multiply
