Answer:
The expression "a-b+c+d+n" represents a combination of variables and arithmetic operations. Let's break it down step by step:
1. First, we need to evaluate "a-b". This means subtracting the value of b from a.
2. Next, we add the result of step 1 to c.
3. Then, we add d to the result of step 2.
4. Finally, we add n to the result of step 3.
To better understand this, let's use some examples:
Example 1:
If a = 5, b = 2, c = 3, d = 1, and n = 4, we can substitute the values into the expression:
5 - 2 + 3 + 1 + 4
First, we evaluate "5 - 2" which equals 3. Then, we add 3 to 3, resulting in 6. Adding 1 to 6 gives us 7, and adding 4 to 7 gives us the final answer of 11.
So, for the given values of a, b, c, d, and n, the expression "a-b+c+d+n" evaluates to 11.
Example 2:
Let's say a = 10, b = 7, c = 2, d = 4, and n = 6:
10 - 7 + 2 + 4 + 6
First, we evaluate "10 - 7" which equals 3. Adding 3 to 2 gives us 5. Adding 4 to 5 gives us 9, and adding 6 to 9 gives us the final answer of 15.
So, for the given values of a, b, c, d, and n, the expression "a-b+c+d+n" evaluates to 15.
In summary, the expression "a-b+c+d+n" represents a series of arithmetic operations performed on the given variables a, b, c, d, and n. By substituting the values of these variables into the expression, we can evaluate it step by step to find the final result.
