If (p>q), which operation does not change the direction of the inequality?यदि (p>q) है, तो किस क्रिया से असमानता की दिशा नहीं बदलती?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: adding (7) to both sidesदोनों पक्षों में (7) जोड़ना
Adding the same number to both sides does not change inequality direction. The sign changes only when multiplying or dividing by a negative number.दोनों पक्षों में समान संख्या जोड़ने से असमानता की दिशा नहीं बदलती। चिन्ह केवल ऋणात्मक गुणा या भाग में बदलता है।
