Which is the only number which is equal to the sum of its digits?
Well, 1 is equal to 1. 9 is equal to 9. So any number from 0 to 9. I do not think this is what is meant by the question. If you mean any number with more than one digit. There is no such number. Because 11 sums to 2. 19 sums to 10. 21 sums to 3. 29 sums to 11. 111 sums 3. 119 sums to 11. The sums do not grow as fast the increase of digits.

Have 1 of each of these digits 1p 2p 5p 10p 20p how many sums can you make using these digits?
10p is not a digit. A digit is an integer in the range 0-9. Leaving that aside, you can make 31 sums from the 5 coins. If you allow 0 as a valid sum, the answer is 32.
How do you estimate decimal sums and differences?
The basic idea is the same as when you estimate sums and differences of larger numbers (which may or may not be integers). You round the numbers to one or two decimal digits, then add them up.
What number is 2 times the sums of its digits?
1+8=9, 9x2=18 so 18 is one answer to this problem
Which are the sums of the hundreds tens and ones for 556 plus 323?

Can sums all rows equal 17 using 1-9 only once?
If you are thinking of a mgic square, the answer is NO. The nine numbers sum to 45 so if you have three rows with equal sums, that sum can only be 45/3 = 15. You can have two rows, each adding to 17, and using the digits only once, but you will not use all digits.
What are the following definitions best sums up the study of geography?

What is the test for divisibility of 11?
Split the number into its alternate digits.Sum the digits in each setIf the difference between their sums is zero (0) or divisible by 11 then the original number is divisible by 11.ExamplesIs 1289324 divisible by 11?Split into alternate digits: 1_8_3_4 and _2_9_2 Sum each set of digits:1_8_3_4 -> 1+8+3+4 = 16_2_9_2 -> 2+9+2 = 13Difference between the sums: 16 - 13 = 3, not divisible by 11; so original number 1289324 is not divisible by 11.Is 19407278 divisible by 11?Split into alternate digits: 1_4_7_7 and _9_8_2_6 Sum each set of digits:1_4_7_7 -> 1+4+7+7 = 19_9_0_2_8 -> 9+0+2+8 = 19Difference between the sums: 19 - 19 = 0; so original number 19407278 is divisible by 11.
