Numerator divided by. Bar models help us to attain an understanding of how a problem needs to be solved and calculated. The bar is a metric unit of pressure but not part of the international system of units si. For many of the symbols below the symbol is usually synonymous with its corresponding concept but in some situations a different convention may be used.
