Answer 2

Let's solve each of these expressions step by step:

1. 26 - (-6) = 26 + 6 = 32
2. 14 - (-18) = 14 + 18 = 32
3. 4.7 - 8.1 = -3.4
4. 7 - (4.9) = 7 - 4.9 = 2.1
5. -5 - (-2.9) = -5 + 2.9 = -2.1
6. -5/12 - (-7/12) = -5/12 + 7/12 = 2/12 = 1/6
7. -3 1/2 - (-1 3/4) = -3.5 + 1.75 = -1.75
8. 2 2/3 - 3/59 = 2.666... - 0.050847... ≈ 2.615152...
9. 2/5 - 0.7 = 0.4 - 0.7 = -0.3
10. -8/15 - (-0.4) = -8/15 + 4/10 = -8/15 + 6/15 = -2/15
11. -3.2 - 2 1/3 = -3.2 - 2.333... ≈ -5.533...
12. 7.8 - 8 1/4 = 7.8 - 8.25 = -0.45

Please note that some of the results are approximate due to decimal places, and I've rounded them to a reasonable number of decimal places. If you need more precision, you can keep the numbers in their decimal form without rounding.
