Math question: What is the sum of the digits of the number 1662 doubled?

To find the sum of the digits, we double each digit of the number 1662. Doubling the thousands digit (1) gives us 2, doubling the hundreds digit (6) gives us 12, doubling the tens digit (6) gives us 12, and doubling the units digit (2) gives us 4. Now, we add up these doubles: 2 + 12 + 12 + 4 = 30. Therefore, the sum of the digits of 1662 doubled is 30.

Math question: If I multiply a number by 6 and then divide the result by 3, I get 1662. What is the original number?

Let's assume the original number is x. According to the question, we have the equation (6x) / 3 = 1662. Simplifying, we get 2x = 1662. Finally, dividing both sides by 2, we find x = 831. Therefore, the original number is 831.

Math question: What is the sum of all the prime numbers between 1662 and 2000?

To find the answer, we need to identify the prime numbers between 1662 and 2000, and then sum them up. Prime numbers in this range include 1667, 1669, 1693, 1697, 1699, 1709, 1721, 1723, 1733, 1741, 1747, 1753, 1759, 1777, 1783, 1787, 1789, 1801, 1811, 1823, 1831, 1847, 1861, 1867, 1871, 1873, 1877, 1879, 1889, 1901, 1907, 1913, 1931, 1933, 1949, 1951, 1973, 1979, 1987, 1993, 1997, 1999. When we add them all up, the sum is 79420. Thus, the sum of all prime numbers between 1662 and 2000 is 79420.
