Пошаговое объяснение:

1. |-7|+|+5|+|+8|+|-10|= 7+5+8+10 = 30;

2. |+5|+|-2|-|+10|+|-9|= 5+2-10+9 = 6;

3. |+18|+|-2|-|-5|-|-15|= 18+2-5-15 = 20-20 = 0.

4. |-10|+|-2|-|-8|+|-5|= 10+2-8+5 = 9.

Answer 2

Let's solve each of the equations step by step:

|-7| + |+5| + |+8| + |-10| = |+5| + |-2| - |+10| + |-9| = |+18| + |-2| - |-5| - |-15| = |-10| + |-2| - |-8| + |-5|

Step 1: |-7| = 7, |+5| = 5, |+8| = 8, |-10| = 10 7 + 5 + 8 + 10 = |+5| + |-2| - |+10| + |-9| = |+18| + |-2| - |-5| - |-15| = |-10| + |-2| - |-8| + |-5|

Step 2: |+5| = 5, |-2| = 2, |+10| = 10, |-9| = 9 7 + 5 + 8 + 10 = 5 + 2 - 10 + 9 = |+18| + |-2| - |-5| - |-15| = |-10| + |-2| - |-8| + |-5|

Step 3: |+18| = 18, |-2| = 2, |-5| = 5, |-15| = 15 7 + 5 + 8 + 10 = 5 + 2 - 10 + 9 = 18 + 2 - 5 - 15 = |-10| + |-2| - |-8| + |-5|

Step 4: |-10| = 10, |-2| = 2, |-8| = 8, |-5| = 5 7 + 5 + 8 + 10 = 5 + 2 - 10 + 9 = 18 + 2 - 5 - 15 = 10 + 2 - 8 + 5

Calculating the final result: 7 + 5 + 8 + 10 = 30 5 + 2 - 10 + 9 = 6 18 + 2 - 5 - 15 = 0 10 + 2 - 8 + 5 = 9

Therefore: |-7| + |+5| + |+8| + |-10| = 30 |+5| + |-2| - |+10| + |-9| = 6 |+18| + |-2| - |-5| - |-15| = 0 |-10| + |-2| - |-8| + |-5| = 9
