In the table $12345.67_{10}$ = 1.234567+04 (floating point), 1.234567+04 doesn't show any difference between the arithematic addition notation, so if the author was not saying "floating point", I would assume 1.234567+04 equals 5.234567, not 12345.67. So how do we differentiate arithemetic addition or subtraction from floating point numbers?
