Order of Operations with Integers

Front

What is the order of operations in mathematics?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed. The acronym PEMDAS is often used to remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

How do you simplify an expression with parentheses?

Back

To simplify an expression with parentheses, first perform the operations inside the parentheses. Then, follow the order of operations for the remaining calculations.

What is the result of 5 - 3 + 2 when following the order of operations?

Back

The correct result is 4. You should subtract first (5 - 3 = 2) and then add (2 + 2 = 4).

How do you handle negative numbers in addition and subtraction?

Back

When adding negative numbers, you move left on the number line. When subtracting a negative number, it is equivalent to adding the positive value of that number.

Front

What is the result of -8 + (6 - 9) ÷ 3?

Back

The result is -9. First, calculate inside the parentheses (6 - 9 = -3), then divide by 3 (-3 ÷ 3 = -1), and finally add to -8 (-8 + -1 = -9).

Front

What does the exponent 3^2 mean?

Back

The exponent 3^2 means 3 multiplied by itself, which equals 9.

Front

What is the result of (-7) - 3^2?

Back

The result is -16. First, calculate the exponent (3^2 = 9), then perform the subtraction (-7 - 9 = -16).

Front

How do you multiply two negative numbers?

Back

When multiplying two negative numbers, the result is positive. For example, -3 * -5 = 15.

Front

What is the result of -3(-5) - 16?

Back

The result is -1. First, multiply -3 and -5 to get 15, then subtract 16 (15 - 16 = -1).

What is the importance of the order of operations in solving mathematical expressions?

Back

The order of operations is crucial because it ensures that everyone interprets and solves expressions in the same way, leading to consistent and correct results.
