PEMDAS

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). It is the order of operations used to solve mathematical expressions.

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

Exponents are calculated after parentheses and before multiplication, division, addition, and subtraction.

Front

In the expression 8÷2x(6²-3³), what should be calculated first?

Back

First, calculate the expression inside the parentheses: (6²-3³) = (36-27) = 9.

Front

What is the result of the expression 4+1x3 using PEMDAS?

Back

Using PEMDAS, you first perform the multiplication: 1x3 = 3, then add: 4+3 = 7.

Front

In the expression 4-1+5x2², what is the order of operations?

Back

First, calculate the exponent: 2² = 4. Then perform multiplication: 5x4 = 20. Finally, perform addition and subtraction from left to right: 4-1+20 = 23.

Front

What is the result of 6x(3²-1)?

Back

First, calculate the expression inside the parentheses: (3²-1) = (9-1) = 8. Then multiply: 6x8 = 48.

Front

How do you simplify the expression 6+(4²-1)?

Back

First, calculate the exponent: 4² = 16. Then simplify inside the parentheses: 16-1 = 15. Finally, add: 6+15 = 21.

Front

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

Back

Following the order of operations ensures that mathematical expressions are solved consistently and correctly, leading to the same result regardless of who performs the calculation.

Front

Can multiplication and division be performed in any order?

Back

No, multiplication and division should be performed from left to right as they appear in the expression.
