Answer 1

Ответ:

1)-2

2)22

3)-1305

4)-18

5)-3,98

Answer 2

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

1. 1.8 + (-3.8) To add these two numbers, you simply combine their values. 1.8 + (-3.8) = -2

2. -55 + (-33) Similar to the previous example, you add the values of these two numbers. -55 + (-33) = -88

3. -4720 + (-3415) Again, add the values of these two numbers. -4720 + (-3415) = -8135

4. -6 - 12 To subtract one number from another, you can consider it as adding the negative value. -6 - 12 = -6 + (-12) = -18

5. -0.38 - 3.6 Subtract the values of these two numbers. -0.38 - 3.6 = -3.98

Therefore, the solutions are:

1. -2
2. -88
3. -8135
4. -18
5. -3.98
