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 simplify the expression 63 ÷ 7 - 3 ⋅ 2 + 4 using PEMDAS?

Back

First, divide 63 by 7 to get 9. Then, multiply 3 by 2 to get 6. The expression becomes 9 - 6 + 4, which simplifies to 7.

Front

What is the exponent form of 4 * 4 * 4 * 4 * 4 * 4 * 4 * 4?

Back

The exponent form is 4^8.

Front

How do you evaluate the expression 4 + 3 - (8 - 6) x 2?

Back

First, solve the parentheses: (8 - 6) = 2. Then, multiply: 2 x 2 = 4. Finally, evaluate: 4 + 3 - 4 = 3.

Front

What is the result of (3 + 4)^2 - 32?

Back

First, calculate (3 + 4) = 7. Then, square it: 7^2 = 49. Finally, subtract 32: 49 - 32 = 17.

Front

What is the order of operations in PEMDAS?

Back

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

Front

What is the difference between multiplication and division in PEMDAS?

Back

Multiplication and division are performed from left to right, meaning you do whichever comes first in the expression.

Front

How do you handle exponents in an expression?

Back

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

Front

What is the result of simplifying the expression 5 + 2 * (3^2 - 1)?

Back

First, calculate the exponent: 3^2 = 9. Then, solve inside the parentheses: 9 - 1 = 8. Finally, multiply: 2 * 8 = 16, and add: 5 + 16 = 21.
