Answer:
-10
Step-by-step explanation:
Given the expression 18 - 4 + 6 - 30
Step 1:
Regroup the integers
= 18+6-4-30
= (18+6) - (4+30)
Step 2:
Evaluate the expressions in parenthesis (add the integers)
18+6 = 24
4+30 = 34
The expression becomes:
= 24-34
Step 3:
Take the differnce of the resulting expression
= 24-34
= -10
Hence the sum of 18 - 4 + 6 - 30 is -10
