Question

problem 4.
all ______ should be done second, starting from the left and working to the right, unless parentheses or fraction bars indicate otherwise.
a. additions and subtractions
b. inverse operations
c. multiplications and divisions
d. decimals and negatives
e. none of the above

Explanation:

To solve this, we recall the order of operations (PEMDAS/BODMAS). The order is Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), then Addition and Subtraction (from left to right). So multiplications and divisions are done second (after exponents/orders) when working left - right, unless parentheses or fraction bars change the order. Option A is for the last step (after multiplication/division). Option B is not related to the order of operations in this context. Option D is about number types, not operations order.

Answer:

C. multiplications and divisions
