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.

What is the value of 3^2?

Back

9

How do you solve 40 + 5^2 - 7⋅4 using PEMDAS?

Back

First, calculate the exponent: 5^2 = 25. Then, perform multiplication: 7⋅4 = 28. Now, solve: 40 + 25 - 28 = 37.

Front

What is the result of 2^4 - 24 ÷ 3 + 1?

Back

First, calculate the exponent: 2^4 = 16. Then, perform the division: 24 ÷ 3 = 8. Now, solve: 16 - 8 + 1 = 9.

Front

How do you simplify (3 + 4)^2 - 32?

Back

First, calculate inside the parentheses: 3 + 4 = 7. Then, calculate the exponent: 7^2 = 49. Finally, subtract: 49 - 32 = 17.

Front

What is the value of 5 x (7 - 2) + (8 + 1)?

Back

First, calculate inside the parentheses: 7 - 2 = 5 and 8 + 1 = 9. Then, multiply: 5 x 5 = 25. Finally, add: 25 + 9 = 34.

Front

What is the order of operations in mathematics?

Back

The order of operations is: 1. Parentheses, 2. Exponents, 3. Multiplication and Division (from left to right), 4. Addition and Subtraction (from left to right).

Front

What is an exponent?

Back

An exponent is a number that shows how many times a base is multiplied by itself. For example, in 3^2, 3 is the base and 2 is the exponent, meaning 3 is multiplied by itself 2 times (3 x 3).

Front

What is the result of 8 - 3 + 2 x 4?

Back

Using PEMDAS, first do the multiplication: 2 x 4 = 8. Then, solve from left to right: 8 - 3 + 8 = 13.

Front

How do you evaluate 6 + 2^3 - 4?

Back

First, calculate the exponent: 2^3 = 8. Then, solve: 6 + 8 - 4 = 10.
