It is easier to simply add two one-digit numbers than to mess about with estimation!
To make the list of two-digit numbers with digits that add up to 10, first write the pairs of single-digit integers that add up to 10. They are (1,9), (2,8), (3,7), (4,6), (5,5). Then recognize that each of these pairs of numbers, except 5, can be combined in two different ways to make two-digit numbers that satisfy the problem. 19 and 91 28 and 82 37 and 73 46 and 64 55 So there are nine two-digit numbers with digits that add up to 10.

Well, butter my biscuits! The two consecutive 4-digit numbers that add up to 9173 are 4586 and 4587. It's as simple as that, sugar!
2000.The smallest four-digit number there can be is 1000. So, add 1000 and 1000 to get 2000, then least sum you can get when adding two four-digit numbers.
You line up the last numbers and then add it!
The two numbers that equal 425 are 212.5 and 212.5. This is because when you add them together, 212.5 + 212.5 equals 425. Another way to think about it is that 425 divided by 2 equals 212.5, so both numbers are the same.

Well, friend, when you add two two-digit numbers together, the sum will always be a two-digit number or a three-digit number, not a four-digit number. It's like mixing different colors on your palette - you'll get a beautiful new shade, but it won't be something completely different. Just keep adding those numbers together and creating something wonderful!
