By trial and error, here's one:
87 + 93 = 156 + 24
1/10 + 8/10 = 9/10
one possible 183 762 945
Through the magic of perms and coms the answer is 729
Nine. Using PEMDAS, you start with 12/4, which is three. Then the problem is 9-3+3, which is basically just 9. Nine.
10
8
There are 360 of them.
To estimate the sum is to guess what the answer is for an addition problem. For example, if it was 8 + 9 you would see what number 8 is close to (like ten) and do the same with number nine and your estimate would be 20.
Nine thousand using standard numerals is 9,000

This is a factorial problem. The first number can be any of ten digits, the second any of nine (because you can't repeat a digit), the third any of eight and the fourth any of the remaining 7 digits. 10x9x8x7=5040 combinations.
