Question

A) |-7| + |+5| + |+8| + |-10| b) |+12| + |-2| -|+10| + |-9| c) |+18| +|-2| - |-5| - |-15| d) |-10| + |-2| - |-8| + |-5|

Answer 1

А) |-7|+|+5|+|+8|+|-10|=7+5+8+10=30
б) |+12|+|-2|-|+10|+|-9|=12+2-10+9=13
в) |+18|+|-2|-|-5|-|-15|=18+2-5-15=0
г) |-10|+|-2|-|-8|+|-5|=10+2-8+5=9

Answer 2

To solve these expressions, simply evaluate the absolute values and then perform the arithmetic operations accordingly.

a) |-7| + |+5| + |+8| + |-10|

|-7| = 7 |+5| = 5 |+8| = 8 |-10| = 10

Now, add them up: 7 + 5 + 8 + 10 = 30

b) |+12| + |-2| - |+10| + |-9|

|+12| = 12 |-2| = 2 |+10| = 10 |-9| = 9

Now, perform the operations: 12 + 2 - 10 + 9 = 13

c) |+18| + |-2| - |-5| - |-15|

|+18| = 18 |-2| = 2 |-5| = 5 |-15| = 15

Now, perform the operations: 18 + 2 - 5 - 15 = 0

d) |-10| + |-2| - |-8| + |-5|

|-10| = 10 |-2| = 2 |-8| = 8 |-5| = 5

Now, perform the operations: 10 + 2 - 8 + 5 = 9

So, the results are: a) 30 b) 13 c) 0 d) 9
