Answer 1

Let's evaluate each expression to see if their sum or difference equals 34.

1. 12 + 24 = 36
2. 1 2 + 2 4 (interpreting it as \( \frac{1}{2} + \frac{2}{4} \)) = \( \frac{1}{2} + \frac{1}{2} = 1 \)
3. 1112 − 16 = 1096
4. 11 12 - 1 6 (interpreting it as \( \frac{11}{12} - \frac{1}{6} \)) = \( \frac{11}{12} - \frac{2}{12} = \frac{9}{12} = \frac{3}{4} \)
5. 35 + 320 = 355
6. 3 5 + 3 20 (interpreting it as \( \frac{3}{5} + \frac{3}{20} \)) = \( \frac{12}{20} + \frac{3}{20} = \frac{15}{20} = \frac{3}{4} \)
7. 78 − 12 = 66
8. 7 8 - 1 2 (interpreting it as \( \frac{7}{8} - \frac{1}{2} \)) = \( \frac{7}{8} - \frac{4}{8} = \frac{3}{8} \)
9. 23 + 112 = 135

None of the expressions evaluate to 34. Thus, none of the expressions have a sum or difference of 34.
