To make 200 using four numbers between 1-9, you can use the following equation: (9 x 9) + (9 x 9) - (9 + 1) = 200. This equation breaks down to (81) + (81) - (10) = 200. By multiplying two nines together twice and subtracting the sum of 9 and 1, you can achieve the target number of 200.
You can't unless something is missing in your question.
3*3*2*1 = 18 of them.
Using only sums and differences, and not necessarily all four numbers, 1, 3, 9 and 27 will make all numbers from 0 to 40.
