Question: If the number 2783 is added to the sum of its digits multiplied by itself, what is the resulting value?

To solve this, calculate the sum of the digits of 2783: 2 + 7 + 8 + 3 = 20. Multiply the sum by itself: 20 * 20 = 400. Finally, add 400 to the original number: 2783 + 400 = 3183. Therefore, the resulting value is 3183.

What is the sum of the digits of the squared number obtained by multiplying 2783 by itself?

To find the squared number, we multiply 2783 by itself: 2783 × 2783 = 7745289. Next, we sum the digits of 7745289: 7 + 7 + 4 + 5 + 2 + 8 + 9 = 42. Therefore, the sum of the digits of the squared number 2783^2 is 42.

Math Question: How many prime numbers are there between 1 and 2783?

To find the number of prime numbers, we can use the Sieve of Eratosthenes. Starting from 2, we mark all the multiples of 2 as composite. Moving to the next unmarked number, which is 3, we mark all its multiples as composite. We continue this process until we reach the square root of 2783. By following this method, we eliminate all the non-prime numbers, and what remains are the primes. Counting the remaining primes gives us the answer. The prime numbers between 1 and 2783 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 277, 281, 283, 293, 307, 311, 313, 317, 331, 337, 347, 349, 353, 359, 367, 373, 379, 383, 389, 397, 401, 409, 419, 421, 431, 433, 439, 443, 449, 457, 461, 463, 467, 479, 487, 491, 499, 503, 509, 521, 523, 541, 547, 557, 563, 569, 571, 577, 587, 593, 599, 601, 607, 613, 617, 619, 631, 641, 643, 647, 653, 659, 661, 673, 677, 683, 691, 701, 709, 719, 727, 733, 739, 743, 751, 757, 761, 769, 773, 787, 797, 809, 811, 821, 823, 827, 829, 839, 853, 857, 859, 863, 877, 881, 883, 887, 907, 911, 919, 929, 937, 941, 947, 953, 967, 971, 977, 983, 991, 997, 1009, 1013, 1019, 1021, 1031, 1033, 1039, 1049, 1051, 1061, 1063, 1069, 1087, 1091, 1093, 109
