<em>DC</em>₃₁ is the entry of the product <em>DC</em> in row 3, column 1, which you get by computing the dot product of the 3rd row of <em>D</em> and the 1st column of <em>C</em> :
{3, -2} • {1, 4} = 3×1 + (-2)×4 = 3 - 8 = -5
Following order of operations rules, do the operation inside parentheses first:
9+7 = 16
Then multiply your result (16) by 4. Result: 64.
36+7 is incorrect (wrong order of operations; see above comment)
