Question: What is the remainder when 6988 is divided by 7, and then multiplied by the square root of 25, subtracted from the cube of 4, divided by 2, and added to the product of 5 and the floor function of the quotient of 6988 divided by 100?

To find the remainder when 6988 is divided by 7, we perform 6988 ÷ 7 = 998 with a remainder of 6. The square root of 25 is 5. The cube of 4 is 4 × 4 × 4 = 64. Dividing 64 by 2 gives 32. The quotient of 6988 ÷ 100 is 69. Multiplying 5 by the floor of 69 gives 5 × 69 = 345. Finally, adding the results together: 6 × 5 - 32 + 345 = 383. Therefore, the final answer is 383.

Question: What is the sum of the digits of 6988 multiplied by the difference between the units and hundreds digit of 6988, divided by the product of the tens and thousands digit of 6988?

To solve the question, we start by finding the digits of 6988. The thousands digit is 6, the hundreds digit is 9, the tens digit is 8, and the units digit is also 8. The sum of the digits of 6988 is 6 + 9 + 8 + 8 = 31. The difference between the units digit and the hundreds digit is 8 - 9 = -1. The product of the tens digit and the thousands digit is 8 * 6 = 48. Now, we calculate the desired expression: (31 * -1) / 48 = -31/48 = -0.6458333333 (rounded to ten decimal places). Therefore, the answer is approximately -0.6458333333.

Math question: What is the largest prime factor of the number 6988?

To find the largest prime factor of 6988, we begin by dividing it by the smallest prime number, which is 2. Dividing 6988 by 2 gives us 3494. Next, we divide 3494 by 2 again, yielding 1747, which is a prime number. Therefore, the largest prime factor of 6988 is 1747.
