Solving the Expression: (-2)(-5) + (-25) x (-7) - (4-6)(-5)
This problem involves several mathematical operations, including multiplication, addition, subtraction, and parentheses. To solve it correctly, we need to follow the order of operations (PEMDAS/BODMAS):
1. Parentheses/Brackets:
- First, we solve the expression inside the parentheses: (4-6) = -2
2. Exponents/Orders:
- There are no exponents in this expression.
3. Multiplication and Division (from left to right):
- (-2)(-5) = 10
- (-25) x (-7) = 175
- (-2)(-5) = 10
4. Addition and Subtraction (from left to right):
- 10 + 175 = 185
- 185 - 10 = 175
Therefore, the solution to the expression (-2)(-5) + (-25) x (-7) - (4-6)(-5) is 175.
