Answer 3

Sure, let's solve the expression step by step:

Given expression: 19 - (7 + 9) + 3 + 23 - (5 + 8) - 10

Step 1: Simplify the innermost parentheses

First, let's simplify the innermost parentheses: 7 + 9 = 16 5 + 8 = 13

The expression now becomes: 19 - 16 + 3 + 23 - 13 - 10

Step 2: Perform addition and subtraction from left to right

Now let's perform addition and subtraction from left to right: 19 - 16 = 3 3 + 3 = 6 6 + 23 = 29 29 - 13 = 16 16 - 10 = 6

Final Answer

After simplifying the expression, we get the final answer: 6.

Therefore, the solution to the given expression 19 - (7 + 9) + 3 + 23 - (5 + 8) - 10 is 6.
