Umkhiqizo uphindaphinda ini? Amanani afanayo nalawo esamba. Lapho $x=$ ('$1$', 'FFD84A'), 1+2=3\displaystyle 1+2=3. Lapho $x=$ ('$2$', 'FFD84A'), ngu-4. Lapho $x=$ ('$3$', 'FFD84A'), ngu-5. Lapho $x=$ ('$4$', 'FFD84A'), ngu-6. Lapho $x=$ ('$5$', 'FFD84A'), ngu-7. Ngalesi sikhathi imiphumela iyaphindaphindwa: Umkhiqizo ngu-3×4×5×6×7=2520\displaystyle 3 \times 4 \times 5 \times 6 \times 7 = 2520. Futhi Ngamanyathelo angu-2, u-x ngu-1, 3 no-5: 3×5×7=105\displaystyle 3 \times 5 \times 7 = 105.
