5 - 3 + 7 - 4
5 - 3 + 7 - 4 = 5 + 7 - 3 - 4 = 12 - 3 - 4 = 9 - 4 = 5.
5 - 3 + 7 - 4
5 - 3 + 7 - 4 = (5 - 3) + (7 - 4) = 2 + 3 = 5.
To solve this expression step-by-step, we will follow the order of operations (BIDMAS).
Step 1: Calculate the substraction first: 5 - 3 = 2.
Step 2: Now, we have: 2 + 7 - 4.
Step 3: Perform the addition: 2 + 7 = 9.
Step 4: Finally, subtract 4 from 9: 9 - 4 = 5.
So, the final answer is 5.
To solve the expression 5 - 3 + 7 - 4, you can follow the order of operations (also known as PEMDAS):
1. Start by solving any operations within parentheses or brackets. In this case, there are no parentheses or brackets, so you move to the next step.
2. Next, solve any exponents or powers. In this case, there are none.
3. Then, perform any multiplication or division operations from left to right. Again, there are none to evaluate.
4. Finally, solve any addition or subtraction operations from left to right.
Now let's break down the expression step by step:
5 - 3 + 7 - 4
First, we subtract 3 from 5, which gives us:
5 - 3 = 2
Now the expression becomes:
2 + 7 - 4
Next, we add 7 to 2:
2 + 7 = 9
Now the expression becomes:
9 - 4
Finally, we subtract 4 from 9:
9 - 4 = 5
Therefore, the final answer to the expression 5 - 3 + 7 - 4 is 5.
