Impossible, as there are not enough numbers to cover all squares.
One example. 12*8+3+7-6 = 100 The key is finding sets of 10s
Yes.
If you must use all digits precisely once then the answer is: 8642, 8624, 8462
To get 1000 using the numbers 1, 2, 3, and 4 only once in an equation, you can use the following mathematical expression: (4 x 2 x 3 x 1) x (4 + 2 + 3 + 1) = 1000. This equation involves multiplication and addition operations using all four numbers exactly once to achieve the desired result of 1000.
add them all together and then divide the answer by the number of numbers.
234, 243, 324, 342, 423, and 432.

Using only sums and differences, and not necessarily all four numbers, 1, 3, 9 and 27 will make all numbers from 0 to 40.
Impossible, as there are not enough numbers to cover all squares.
One example. 12*8+3+7-6 = 100 The key is finding sets of 10s
You have 4 options for the first digit, 3 for the second, 2 for the third. Multiplying all this you get 4 x 3 x 2 = 24 options.
Yes.
If you must use all digits precisely once then the answer is: 8642, 8624, 8462
All numbers can be expressed using exponents.
There are 210 of them, and I regret that I do not have the time to list them all.
