Is it incorrect to say number 3 is 'infront of' letter B in "B 3"? considering that front is a position a head of something [closed]

Transposing dimensions to others is confusing in general as neither the B nor the 3 is in front or behind. One is to the left and one is to the right when talking about position. A clearer way could be to speak of the order of appearance. The B comes first and the 3 follows, which would be understood as we read from left to right.
