Order of Operations (School Challenge)

Front

What is the Order of Operations?

Back

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

Front

What does the acronym PEMDAS stand for?

Back

PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

What is the first step in the Order of Operations?

Back

The first step is to solve expressions inside Parentheses.

Front

What is the second step in the Order of Operations?

Back

The second step is to calculate Exponents.

Front

What do you do after solving Parentheses and Exponents?

Back

After solving Parentheses and Exponents, perform Multiplication and Division from left to right.

Front

What is the last step in the Order of Operations?

Back

The last step is to perform Addition and Subtraction from left to right.

If you have the expression 3 + 5 × 2, what is the correct answer?

Back

The correct answer is 13. (First, multiply 5 × 2 = 10, then add 3 + 10 = 13.)

Front

In the expression (4 + 6) × 2, what should you calculate first?

Back

You should calculate the expression inside the Parentheses first: (4 + 6) = 10.

What is the Greatest Common Factor (GCF) of 24 and 30?

Back

The GCF of 24 and 30 is 6.

Front

How do you find the GCF using prime factorization?

Back

To find the GCF using prime factorization, list the prime factors of each number, then multiply the lowest powers of common prime factors.
