### Example Question #7 : Operations In Expressions

When evaluating the expression

,

which of the five operations must be carried out third?

**Possible Answers:**

Squaring

Multiplication

Subtraction

Addition

Division

**Correct answer:**

Squaring

By the order of operations, any operations within parentheses must be carried out first; there are two here, the addition and the subtraction. After this is done, the exponent, or squaring, must be worked before the other operations. Squaring, the third operation, is therefore the correct answer.

### Example Question #8 : Operations In Expressions

When evaluating the expression

,

in which order must you work the three operations?

**Possible Answers:**

Multiplication, cubing, subtraction

Cubing, multiplication, subtraction

Subtraction, multiplication, cubing

Cubing, subtraction, multiplication

Subtraction, cubing, multiplication

**Correct answer:**

Cubing, multiplication, subtraction

By the order of operations, in the absence of grouping symbols, the exponent (represented here by cubing) must be worked first. The multiplication must be worked second, followed by the subtraction.

### Example Question #28 : How To Subtract Integers
