Solve equations by arranging numbers and arithmetic operations.
Example 1
Arrange the numbers and arithmetic operations to reach a total of 28.
* 4 8 4 -
= 28
Solution: (4*8) - 4 = 28
Example 2
Arrange the numbers and arithmetic operations to reach a total of 8.
15 5 / 5
= 8
Solution: (15/5) + 5 = 8
1. Add the digits 16, and 17, in order to reach a total of 100.
16 + 16 + 17 + 17 + 17 + 17 = 100
2. Arrange the numbers and arithmetic operations to reach a total of four.
- 6 2 8 +
= 4
8 - 6 + 2 = 4
3. Find the correct arithmetic operations and solve the equation.
3 3 3 = 6
(3*3) - 3 = 6
4. Find the correct arithmetic operations and solve the equation.
7 7 7 = 6
7 - (7/7) = 6
5. The following equation lists all digits 1-9 in increasing order and equals 100.
12+3-4+5+67+8+9 = 100
Using only addition and subtration make similar equations.
These are only a few answers out of many possible solutions.
123-4-5-6-7+8-9=100
123+45-67+8-9 = 100
1+23-4+5+6+78-9=100
