Solving (-2)(-5) + 7
This expression involves multiplication and addition. To solve it, we need to follow the order of operations, often remembered by the acronym PEMDAS or BODMAS:
- Parentheses (or Brackets)
- Exponents (or Orders)
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Let's break down the expression step-by-step:
-
Multiplication: First, we multiply (-2) and (-5). Remember that multiplying two negative numbers results in a positive number. (-2)(-5) = 10
-
Addition: Now we add 7 to the product we just calculated. 10 + 7 = 17
Therefore, the solution to (-2)(-5) + 7 is 17.
