2) 9+1.000=1.009
3) 700-8•2=700-16=684
4) 340+10•5=340+50=390

Answer 2

42+20=62
9+1000=1009
700-8*2=700-16=684
340+10*5=340+50=390

Answer 3

Let's calculate the results of the given arithmetic expressions:

1. 42 + 20 = 62
2. 9 + 1000 = 1009
3. 700 - 8 * 2 = 700 - 16 = 684
4. 340 + 10 * 5 = 340 + 50 = 390

So, the results are:

1. 42 + 20 = 62
2. 9 + 1000 = 1009
3. 700 - 8 * 2 = 684
4. 340 + 10 * 5 = 390
