Ann initially had a number of stickers represented by the equation 7y + 12, where y is the number of stickers given to each of her 7 friends. After distributing the stickers, she was left with 12 stickers. When each friend received 9 stickers, the total number of stickers Ann had at first was calculated as 7 times 9 plus 12, resulting in 75 stickers. The calculations confirm the initial equations and provide clarity on the distribution of stickers.

Thread 'Erroneously finding discrepancy in transpose rule'

Obviously, there is something elementary I am missing here. To form the transpose of a matrix, one exchanges rows and columns, so the transpose of a scalar, considered as (or isomorphic to) a one-entry matrix, should stay the same, including if the scalar is a complex number. On the other hand, in the isomorphism between the complex plane and the real plane, a complex number a+bi corresponds to a matrix in the real plane; taking the transpose we get which then corresponds to a-bi...
