Tick (✓) one box to identify the operator that returns the quotient of a calculation with the fractional part discarded. A / □ B DIV □ C ^ □ D MOD □ [1]

Choice B (DIV) is correct because: In computer science and Cambridge IGCSE pseudocode, DIV represents integer division. Integer division divides one integer by another and returns only the integer portion of the quotient, completely discarding (truncating) any fractional or decimal remainder without rounding. For example, evaluating the expression \( 7 \text{ DIV } 2 \) yields \( 3 \), since \( 7 \div 2 = 3.5 \) and discarding the fractional part \( 0.5 \) leaves \( 3 \). This matches the definition given in the question precisely. Choice A (/) is incorrect because: The forward slash (/) is the standard division operator. It returns a real (floating-point) number that includes the fractional part. For example, evaluating \( 7 / 2 \) results in \( 3.5 \), meaning the fractional part is preserved rather than discarded. Choice C (^) is incorrect because: The caret symbol (^) is used for exponentiation (raising a base number to a power). It does not perform division or return a quotient. For example, evaluating \( 2 \text{ \textasciicircum } 3 \) results in \( 2^3 = \mathbf{8} \). Choice D (MOD) is incorrect because: The MOD (modulo) operator returns the remainder of an integer division, not the quotient. A common misconception is confusing DIV (which keeps the quotient and drops the remainder) with MOD (which keeps the remainder and drops the quotient). For example, evaluating \( 7 \text{ MOD } 2 \) results in \( 1 \), which is the remainder left over after dividing \( 7 \) by \( 2 \).
