Mac breaks down the numbers 291 and 407 into their place values. For 291, he adds 200 (hundreds), 90 (tens), and 1 (ones), resulting in 200 + 90 + 1 = 291. For 407, he adds 400 (hundreds), 0 (tens), and 7 (ones), resulting in 400 + 0 + 7 = 407. To find the total, he adds the sums of each place value: 200 + 400 (hundreds), 90 + 0 (tens), and 1 + 7 (ones), which gives him the final sum of 698.
There is no four digit number where the ones is twice the tens, the hundreds is five less than the ones, and the thousands is the sum of the tens and hundreds. int ones, tens, hundreds, thousands; for (thousands=1; thousands<10; thousands++) { /**/ for (hundreds=0; hundreds<10; hundreds++) { /**/ /**/ for (tens=0; tens<10; tens++) { /**/ /**/ /**/ for (ones=0; ones<10; ones++) { /**/ /**/ /**/ /**/ if (ones != 2 * tens) break; /**/ /**/ /**/ /**/ if (hundreds != ones - 5) break; /**/ /**/ /**/ /**/ if (thousands != tens + hundreds) break; /**/ /**/ /**/ /**/ printf ("dd\n", thousands, hundreds, tens, ones); /**/ /**/ /**/ } /**/ /**/ } /**/ } }

224 has.
Your correct answer is hundreds place because you have your ones period like ones tens hundreds same with the thousands period ones tens hundreds.
The number is 729.
