To solve the expression -10-9 - -5-4 + 5 + 5, we need to follow the order of operations, which is also known as the PEMDAS rule.
1. First, we deal with any parentheses or brackets. In this case, there are none.
2. Next, we evaluate any exponents or powers. There are none in this expression.
3. Then, we move on to multiplication and division. Again, there are no multiplication or division operations to perform.
4. After that, we perform addition and subtraction operations from left to right. Let's break it down step by step:
-10 - 9 = -19
-5 - (-4) = -5 + 4 = -1
-19 - (-1) = -19 + 1 = -18
-18 + 5 = -13
-13 + 5 = -8
So, the final result is -8.
To simplify the expression -10-9- -5-4 5 5, we need to follow the order of operations (PEMDAS/BODMAS):
Step 1: Simplify the subtraction -9 - (-5)
-9 - (-5) is equivalent to -9 + 5, which equals -4.
Step 2: Substitute the result of step 1 into the expression.
-10 - (-4) - 4 5 5
Step 3: Simplify the next subtraction -10 - (-4)
-10 - (-4) is equivalent to -10 + 4, which equals -6.
Step 4: Substitute the result of step 3 into the expression.
-6 - 4 5 5
Step 5: Perform multiplication as the last operation.
-6 - 4 * 5 * 5
Step 6: Multiply 4 * 5 * 5
4 * 5 * 5 is equal to 20 * 5, which equals 100.
Step 7: Substitute the result of step 6 into the expression.
-6 - 100
Step 8: Perform the final subtraction.
-6 - 100 is equal to -106.
Therefore, the simplified expression -10-9- -5-4 5 5 is equal to -106.
