Example Question #27 : Concepts
Evaluate:
Evaluate the numerator first by order of operations.
Evaluate the denominator by order of operations. Double negatives will equal a positive.
Divide the numerator with the denominator and reduce the fraction.
Example Question #28 : Concepts

When multiplying two negative numbers, their product becomes positive. Thus,
Example Question #29 : Concepts
When evaluating the expression
,
which operation must be performed second?
Subtraction
Addition
Multiplication
Division
Multiplication
According to the order of operations, the operation inside the parentheses, which is the subtraction, is performed first.
This leaves a multiplication, a division, and an addition. By the order of operations, the multiplication and the division come next in left-to-right order; we choose the one that is to the left, which is the multiplication.
Example Question #30 : Concepts
When evaluating the expression
,
which operation must be performed third?
Division
Addition
Multiplication
Subtraction
Subtraction
According to the order of operations, since no grouping symbols are present (the parentheses are setting apart a negative number, not an operation), multiplication and the division must be performed, left to right, then the addition and the subtraction must be performed, left to right.
This means that the first two operations to be performed are the multiplication and the division. This leaves a subtraction and an addition; since the subtraction is at left, it is the third operation performed.
