75-30=45
64-20=44

Answer 3

Sure, let's solve these arithmetic expressions step by step:

1. 57 - 40 = 17
2. 60 + 30 = 90
3. 39 + 10 = 49
4. 48 - 20 = 28
5. 75 - 30 = 45
6. 64 - 20 = 44

So, the results are:

1. 17
2. 90
3. 49
4. 28
5. 45
6. 44

Note: The statement "1 столбик сложение 2 вычитание" translates to "1 column addition 2 subtraction," which means we performed the calculations using a columnar method for addition and subtraction.
