Answer 3

To calculate the expression 7.8 - (-3.10), you need to follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction:

1. Start by evaluating the expression inside the parentheses: -(-3.10) = 3.10 (negating a negative number makes it positive).

2. Now the expression becomes: 7.8 - 3.10

3. Finally, subtract the two numbers: 7.8 - 3.10 = 4.70

So, 7.8 - (-3.10) is equal to 4.70.
