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

What is the second step in the order of operations?

Back

The second step is to evaluate Exponents.

Front

In the expression 3 + 4 × 2, which operation do you perform first according to PEMDAS?

Back

You perform the multiplication first: 4 × 2 = 8, then add 3 to get 11.

Front

Evaluate the expression: 5 + (3 × 2) - 4.

Back

First, calculate inside the parentheses: 3 × 2 = 6. Then, 5 + 6 - 4 = 7.

Front

What is the result of 2^3 + 4 × 5?

Back

First, calculate the exponent: 2^3 = 8. Then, 4 × 5 = 20. Finally, 8 + 20 = 28.

Front

If a = 2 and b = 3, evaluate 4a + 5b.

Back

Substituting the values: 4(2) + 5(3) = 8 + 15 = 23.

Front

What is the result of 10 - 2^2 + 3 × 4?

Back

First, calculate the exponent: 2^2 = 4. Then, 3 × 4 = 12. Finally, 10 - 4 + 12 = 18.

Front

Evaluate: (6 + 2) × 3 - 4.

Back

First, calculate inside the parentheses: 6 + 2 = 8. Then, 8 × 3 = 24. Finally, 24 - 4 = 20.

Front

What is the value of 7 + 3 × (10 - 2)?

Back

First, calculate inside the parentheses: 10 - 2 = 8. Then, 3 × 8 = 24. Finally, 7 + 24 = 31.
