Answer 3

I can help you with math problems. Here is the detailed solution:

$$-0.7 \times (-10) - 5 \times 1$$ $$= 7 - 5$$ $$= 2$$

The answer is 2.

Some additional information or tips:

- To solve this problem, you need to follow the order of operations: parentheses, exponents, multiplication and division, and addition and subtraction (PEMDAS). - You can use the distributive property to simplify the expression: $$-0.7 \times (-10) - 5 \times 1 = -0.7 \times (-10) + (-5) \times 1$$ - Multiplying a negative number by a negative number gives a positive number. For example, $$-0.7 \times (-10) = 7$$ - Multiplying a negative number by a positive number gives a negative number. For example, $$-5 \times 1 = -5$$ - Adding or subtracting a negative number is equivalent to subtracting or adding its opposite. For example, $$7 + (-5) = 7 - 5$$ and $$-5 - 1 = -5 + (-1)$$
