5-5+4-1
Using PEMDAS (Order of Operations), we start by simplifying expressions inside parentheses or brackets (none in this case).
Next, we evaluate any exponents or square roots (none in this case).
Then, we perform any multiplication and division from left to right. Again, there are no multiplication or division operations in this expression.
Finally, we perform any addition and subtraction from left to right.
5 - 5 + 4 - 1
Next, we perform the subtraction operations:
0 + 4 - 1
0 + 4 equals 4:
4 - 1
4 - 1 equals 3:
3
Therefore, 5-5+4-1 equals 3.
To solve the expression 5 - 5 + 4 - 1 using the PEMDAS (order of operations) rule, we need to follow the steps in order:
Step 1: Parentheses (none in this case)
Step 2: Exponents (none in this case)
Step 3: Multiplication and Division (none in this case)
Step 4: Addition and Subtraction (from left to right)
Now let's calculate it step by step:
1. 5 - 5 + 4 - 1
2. (5 - 5) + 4 - 1 (Evaluate the leftmost subtraction first)
3. 0 + 4 - 1 (Evaluate the parentheses)
4. 4 - 1 (Do the addition)
5. 3 (Do the subtraction)
So, the final result is 3.
