17 = (4+2)*3 - 1
It can be: 2*3+4+1 = 11
4 + 3 + 2 - 1 = 8
2^(4+1)-3
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.
17 = (4+2)*3 - 1
It can be: 2*3+4+1 = 11
3*(2+4)-1 = 17
4*4*2+2*3
4(2+3)-1=19
Ah, what a happy little challenge! To get the number 13 using only the digits 1, 2, 3, and 4, you can add 1, 2, 3, and 4 together. That would give you 10, then you can add 3 to that to get 13. Just remember, there are no mistakes, only happy accidents in math!
4 + 3 + 2 - 1 = 8
(1+4) x (2 x 3)
How about: 2*(1+3+4) = 16
2^(4+1)-3
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.
