Consider the following statements: DATAENDFLAG is off; ERROR equals 0; and SUM is less than 1024. Express the following sentences in symbolic notation: (i) (ii) (iii) (iv) DATAENDFLAG is off, ERROR equals 0, and SUM is less than 1024. DATAENDFLAG is off but ERROR is not equal to 0. DATAENDFLAG is off; however, ERROR is not 0 or SUM is greater than or equal to 1024. Either DATAENDFLAG is on or it is not the case that both ERROR equals 0 and SUM is less than 1024. (v) If DATAENDFLAG is off and SUM is less than 1024, then ERROR equals 0.
