My child has homework stating the following. Using only the numbers 1, 2. 3 & 4 and the order of operations make problems that have the answers of 1 to 50. Use each digit only once per problem. Use +, -, x, (), exponents or use 2 digits to form a 2 digit number Example 1,2=21 or 12. No Division.

We have been able to do all the problems except finding the answers of 7, 22, 31, 34, 42, 43 and 50.

Can you help us? Thank you.

Here are some examples----

3 squared - 4 + 1
=9 - 4 + l
=5 + 1
=6

24 + 3 + 1
=27 + 1
=28

(4-3)x1x2
=1x1x2
=1x2
=2

Hi Dorothy,

7 = (4+1)*2 - 3
22 = 21 + 4 - 3
31 = (2^3)*4 - 1
34 = 34*(1^2)
42 = 42*(1^3)
43 = 43*(1^2)
50 = 13*4 - 2

Cheers,
Claude
