Math Question: What is the sum of the digits of the number 9838 multiplied by the difference between its largest and smallest digit?

To find the sum of the digits of 9838, we calculate 9 + 8 + 3 + 8 = 28. Then, the difference between the largest and smallest digit is 9 - 3 = 6. Multiplying these, we get 28 * 6 = 168. Therefore, the answer is 168.

Math question: If the number 9838 is multiplied by 3, divided by 5, and then increased by 7, what is the result?

Let's solve it step by step. First, multiplying 9838 by 3 gives 29514. Dividing this by 5 yields 5902.8. Finally, increasing this result by 7 gives 5909.8. Therefore, the final result is 5909.8.

Math question: Find the sum of all the prime numbers less than 9838 that are also multiples of 5, excluding 5.

To find the solution, we need to identify the prime numbers less than 9838 that are divisible by 5, excluding 5 itself. The prime numbers that meet this condition are 5, 10, 15, 25, 35, 40, 55, 65, 85, 100, 115, 145, 175, 190, 205, 235, 245, 275, 305, 325, 335, 355, 365, 385, 415, 445, 475, 485, 505, 515, 535, 565, 595, 625, 635, 655, 685, 715, 725, 735, 745, 755, 775, 785, 805, 835, 865, 875, 925, 935, 965, 985, 1000, 1015, 1035, 1045, 1065, 1075, 1085, 1095, 1105, 1125, 1155, 1165, 1185, 1205, 1225, 1235, 1265, 1285, 1295, 1305, 1315, 1325, 1335, 1345, 1355, 1365, 1375, 1395, 1405, 1425, 1435, 1455, 1485, 1495, 1515, 1525, 1535, 1545, 1555, 1565, 1575, 1605, 1625, 1655, 1665, 1685, 1715, 1755, 1765, 1795, 1805, 1815, 1835, 1865, 1875, 1905, 1935, 1945, 1955, 1965, 1975, 1985, 1995, 2005, 2035, 2055, 2085, 2095, 2105, 2115, 2125, 2145, 2155, 2165, 2185, 2215, 2255, 2265, 2305, 2325, 2345, 2355, 2375, 2385, 2415, 2425, 2445, 2455, 2465, 2475, 2505, 2535, 2555, 2595, 2625, 2655, 2665, 2675, 2685, 2695, 2705, 2715, 2725, 2735, 2745, 2755, 2775, 2785, 2805, 2825, 2855, 2865, 2895, 2905, 2925, 2955, 2965, 2975, 2995,
