How can you make 7 by only using the digits 1, 2, 3, and 4? You can put two numbers together (ie 12 or 34). You can use the operations: addition, subtraction, multiplication, (NO DIVISION!!), exponents, and parentheses any way you want!! Please help!!!!
I also need 13, 17, and 39!!!!!!!
1, 2, 3, 4 to make 7
(4+3)x(2-1)
13
(4x3)+(2-1)
17 and 39, I can't think of..keep playing around with the numbers.
To make 7 using the digits 1, 2, 3, and 4, you can follow these steps:
1. Start with the number 4.
2. Subtract 3 from 4: 4 - 3 = 1.
3. Multiply 1 by 4: 1 * 4 = 4.
4. Finally, add 3 to 4: 4 + 3 = 7.
Therefore, 7 can be made using the digits 1, 2, 3, and 4.
To make 13 using the same digits, you can follow these steps:
1. Start with the number 4.
2. Multiply 4 by 3: 4 * 3 = 12.
3. Add 1 to 12: 12 + 1 = 13.
Therefore, 13 can be made using the digits 1, 2, 3, and 4.
To make 17 using the same digits, you can follow these steps:
1. Start with the number 4.
2. Multiply 4 by 3: 4 * 3 = 12.
3. Add 2 to 12: 12 + 2 = 14.
4. Add 3 to 14: 14 + 3 = 17.
Therefore, 17 can be made using the digits 1, 2, 3, and 4.
To make 39 using the same digits, you can follow these steps:
1. Start with the number 4.
2. Multiply 4 by 3: 4 * 3 = 12.
3. Add 2 to 12: 12 + 2 = 14.
4. Multiply 14 by 3: 14 * 3 = 42.
5. Subtract 3 from 42: 42 - 3 = 39.
Therefore, 39 can be made using the digits 1, 2, 3, and 4.
To find different combinations of the digits 1, 2, 3, and 4 that can create the desired result, we can use the following operations: addition (+), subtraction (-), multiplication (*), exponents (^), and parentheses ( ) for grouping.
1. To make 7:
- 4 + 3 = 7
2. To make 13:
- 4 + 4 + 4 + 1 = 13
3. To make 17:
- (4 + 4) * (2 - 1) = 17
4. To make 39:
- 4 * ((2 ^ 3) + 1) = 39
Remember, there may be other valid combinations as well. These are just a few examples.
