Section 1 - Order of operations with Algebra Flashcards
What is the order of operations in mathematics?
The order of operations is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), often abbreviated as PEMDAS.
True or False: In the order of operations, multiplication always comes before addition.
True
Fill in the blank: The acronym PEMDAS stands for ___.
Parentheses, Exponents, Multiplication and Division, Addition and Subtraction
What does the ‘P’ in PEMDAS represent?
Parentheses
What does the ‘E’ in PEMDAS represent?
Exponents
Solve: 3 + 5 × 2.
13
Solve: (4 + 6) × 2.
20
What is the first step in the order of operations?
Solve expressions in parentheses.
True or False: You should always solve exponents before multiplication.
True
What is the result of 2 + 3 × (4 - 1)?
11
What should you do first in the expression: 7 - (3 + 2) × 2?
Solve the parentheses first.
Solve: 2^3 × 3.
24
What does the expression 10 ÷ 2 + 3 represent when applying the order of operations?
First divide 10 by 2, then add 3, resulting in 8.
Solve: (5 + 3)² - 10.
54
In the expression 8 - 2 × 3 + 1, which operation is performed first?
Multiplication (2 × 3)
True or False: In the expression 6 + 4 ÷ 2, you perform addition before division.
False
What is the result of the expression: 4 × (5 - 3) + 2?

Solve: 12 ÷ (2 + 4) × 3.
6
What is the result of 5 + 2 × 3 - 1?
10
What does the expression (3 + 5) × (2 - 1) equal?
8
True or False: You can perform addition before multiplication if it is written first.
False
Fill in the blank: The expression 9 - 4 ÷ 2 × 3 evaluates to ___.
3
What is the final answer for the expression 5 + 3 × 2 - 1?
10
Solve: 10 - (2 + 3) × 2.
0
What is the value of the expression 3 × (2 + 4) - 5?
15
True or False: In the expression 7 + 8 ÷ 4, you should divide before adding.
True
What is the result of 6 + 2 × (5 - 3)?
10
Solve the expression: (8 - 2) × (3 + 1).
24
What is the order of operations when dealing with algebraic expressions?
Follow PEMDAS just as with numerical expressions.
Fill in the blank: The expression 4 × (x + 2) when x = 3 evaluates to ___.
20
What is the result of 2(x + 3) when x = 4?
14
True or False: The order of operations does not change when variables are included.
True
