 From the set {0, 1, 2, 3, 4, 5, 6}, select two distinct numbers a, b to form the complex number a+bi, where the number cannot be real (i.e., b cannot be 0). Calculate the total number of such imaginary numbers that can be formed. Express your answer as a numerical value. Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags.<|im_end|>
