Order of Operations pt 2

Front

What does 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 solving an expression using PEMDAS?

Back

The first step is to solve any operations inside Parentheses.

Front

How do you handle Exponents in PEMDAS?

Back

You calculate the value of the exponent before performing multiplication, division, addition, or subtraction.

Front

In the expression 2 x 11 - 12 ÷ 2, what operation should be performed first according to PEMDAS?

Back

The division (12 ÷ 2) should be performed first.

Front

What is the result of the expression 8 x 18 ÷ 4 + 15?

Back

The result is 51.

Front

How do you approach solving (7 x 8 - 4) ÷ (6 - 2) using PEMDAS?

Back

First, solve the operations inside the parentheses: (7 x 8 - 4) = 52 and (6 - 2) = 4, then divide 52 by 4.

Front

What is the value of 2³ x 3²?

Back

The value is 72.

Front

How do you simplify the expression 5² - 8?

Back

First, calculate 5² = 25, then subtract 8 to get 17.

Front

What is the importance of the order of operations in mathematics?

Back

The order of operations ensures that mathematical expressions are solved consistently and correctly.

Front

Can you give an example of an expression that requires all parts of PEMDAS?

Back

Sure! An example is: (3 + 5) x 2² - 4 ÷ 2.
