Audio mixing using mixed mode arithmetic

Can anybody help me with this problem? (using mixed mode arithmetic)

Also, if possible, could you explain it ?

Thank you for your time and effort in advance !! :)

function mixed_output = mixit(tracks, weights)
    % Convert uint16 audio data to [-1, 1] range
    normalized_tracks = double(tracks) / 32767.5 - 1;

    % Multiply each track with its corresponding weight
    mixed_output = normalized_tracks * weights(:);

    % Check if any value is outside the [-1, 1] range
    max_value = max(abs(mixed_output));
    if max_value > 1
        % Scale the output to fit within the [-1, 1] range
        mixed_output = mixed_output / max_value;
    end
end
