By trial and error, here's one:
87 + 93 = 156 + 24
1/10 + 8/10 = 9/10

You can make nine using four twos by combining addition, multiplication, and parentheses. One way to express this is: ( (2 + 2) \times 2 + 2 = 9 ). Here, you first add two twos to get four, multiply that by another two to get eight, and then add the last two to reach nine.
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
You can make 10 using nine 1s by arranging them in the following mathematical expression: (111 - 11 = 100). Another way is to use addition and parentheses: ( (1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1) = 9 + 1 = 10).
8
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.
There are 360 of them.
