Question

Реши с объяснением. 456+252= 690+188= 23+338=

Answer 1

456+252=708; 690+188= 878; 23+338=361

Answer 2

456 + 252 = 708

Explanation: To add these two numbers, we start by adding the digits in the ones place, which gives us 6. Then, we move on to the tens place and add the digits there, which gives us 5 + 5 = 10. Since the sum of the digits in the tens place is greater than 9, we carry the 1 to the hundreds place. Finally, we add the digits in the hundreds place, which gives us 4 + 2 + 1 = 7. Combining these results, we have 708 as the sum of 456 and 252.

690 + 188 = 878

Explanation: Similar to the previous example, we start by adding the digits in the ones place, which gives us 0 + 8 = 8. Then, we move on to the tens place and add the digits there, which gives us 9 + 8 = 17. Since the sum of the digits in the tens place is greater than 9, we carry the 1 to the hundreds place. Finally, we add the digits in the hundreds place, which gives us 6 + 1 = 7. Combining these results, we have 878 as the sum of 690 and 188.

23 + 338 = 361

Explanation: When adding the digits in the ones place, we have 3 + 8 = 11. Since the sum of the digits in the ones place is greater than 9, we carry the 1 to the tens place. Then, we add the digits in the tens place, which gives us 1 + 3 + 3 = 7. Finally, we add the digits in the hundreds place, which gives us 0 + 2 = 2. Combining these results, we have 361 as the sum of 23 and 338.
