add them all together and then divide the answer by the number of numbers.
Using only sums and differences, and not necessarily all four numbers, 1, 3, 9 and 27 will make all numbers from 0 to 40.
234, 243, 324, 342, 423, and 432.
Impossible, as there are not enough numbers to cover all squares.
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.
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.
If you must use all digits precisely once then the answer is: 8642, 8624, 8462
Any number using all ten digits once each, and ending in 0, 2, 4, 6 or 8 will do.
One example. 12*8+3+7-6 = 100 The key is finding sets of 10s
Assuming you have to use all the digits and use each one exactly once: 135679.
There is none. You can make a sentence using all the letters, but some of them have to be duplicated.
We must put an end to piracy, once and for all.
Put numbers lock, then hold alt, and press J I. Then let it all go all at once. ☼☼
There are 175 solutions all together.
