Evaluate: 3 – 10 + 4 – 8
To solve this expression, we will follow the order of operations, which states that we perform any calculations inside parentheses first, then do any multiplication or division from left to right, and finally any addition or subtraction from left to right.
3 - 10 + 4 - 8
Starting from left to right, we perform the subtraction:
(3 - 10) + 4 - 8
-7 + 4 - 8
Next, we continue with the remaining addition and subtraction:
-3 - 8
Finally, we perform the last subtraction:
-11
Therefore, the expression 3 - 10 + 4 - 8 evaluates to -11.
To evaluate the expression 3 – 10 + 4 – 8, you need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and finally addition and subtraction (from left to right).
Here is the step-by-step evaluation:
Step 1: Perform the addition and subtraction from left to right.
3 – 10 + 4 – 8 becomes -7 + 4 – 8.
Step 2: Continue performing the addition and subtraction from left to right.
-7 + 4 – 8 becomes -3 – 8.
Step 3: Perform the final subtraction.
-3 – 8 equals -11.
Therefore, the evaluation of the expression 3 – 10 + 4 – 8 is -11.
To evaluate this expression, let's break it down step by step:
Step 1: Subtract 10 from 3.
3 - 10 = -7
Step 2: Add 4 to the result from step 1.
-7 + 4 = -3
Step 3: Subtract 8 from the result from step 2.
-3 - 8 = -11
Therefore, the value of the expression 3 – 10 + 4 – 8 is -11.
