Assuming your count starts at zero, the number 9 appears a total of 20 times (9, 19, 29, 39, 49, 59, 69, 79, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99). The same will hold true for every number between 1 and 9. In the case of zero, it will appear 11 times if you start your count at zero, and ten times if you start your count at 1.
The Opposite of 9 depends on how far you can count up to with the exception of infinity. If you can count up to 100, then the opposite of 9 would be 100 - 9 which is 91. If you can count up to 10000000000, then it is just 10000000000 - 9 which is 9999999991. These are the answers to every number you want the opposite of. You take the number you are thinking of and take that away from the number you can count up to. You may get negative answers too. I can count up to 9999999999999999. this is 999 quadrillion, 999 trillion, 999 billion, 999 million, 999 thousand, 9 hundred and 99. i don't know what comes next. to find the opposite of 9, i just take that away. to give me 9999999999999990. i would gety a negative answert if is said to find the opposite of a googolian (1 with 100 zeroes)! i won't write it out. ----
20. There are 11 in the 90 series, plus 9 in the 9, 19, 29, 39 series.

Twenty times.
you can image the 3 digits as a counter 0 0 1 0 0 2 ... ... ... 9 9 8 9 9 9 every digit uses 100 times a 6..... 100*3 digits = 300 sixes :)

The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. Therefore, if you count both 1 and 100, it has 9 factors.
For example if its 9 + 9, count up to nine twice! so you are adding 9 and 9, hope it helped
It is 11*9 = 99
9 x 9 = 81 because if you count 9 times it would make up or be 81
You can check which number from 1 to a 100 are squares of other numbers for yourself. Here's how: Start with 1 and count up, squaring the number and recording the result. Example: 12 = 1 22 = 4 32 = 9 . . . 102 = 100 The number 1, 3, 9 . . . 10 are squares Now, fill in the rest
