Matrices and determinants

Is this true in every case because I've learnt that AB may not be equal to BA in matrices

Correct

AB is not always equal to BA, true

If A transpose=A inverse, then AA Transpose = A TransposeA = I

Otherwise, AA tranpose and A transposeA are not equal,but, they are symmetrical
