You're very welcome. :-)
To solve the expression +3-(-3)-(-7), we need to follow the order of operations or PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right):
1. Start by simplifying any expressions inside parentheses. In this case, we don't have any parentheses to simplify.
2. Next, we tackle the subtraction operation. To subtract a negative value, you can think of it as adding a positive value. So, -(-3) becomes +3, and -(-7) becomes +7.
Now let's substitute these values back into the original expression:
+3 + 3 + 7
3. Finally, we perform the addition operations from left to right:
+3 + 3 = +6
+6 + 7 = +13
Therefore, +3-(-3)-(-7) simplifies to +13.
