🔢 Ascending and Descending Order / आरोही और अवरोही क्रम
Ascending order means arranging numbers from smallest to largest. छोटी संख्या से बड़ी संख्या के क्रम में संख्याओं को व्यवस्थित करना आरोही क्रम (Ascending Order) कहलाता है।
Descending order means arranging numbers from largest to smallest. बड़ी संख्या से छोटी संख्या के क्रम में संख्याओं को व्यवस्थित करना अवरोही क्रम (Descending Order) कहलाता है।
