Lab 21: 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).

Front

What is the first step in solving an expression using PEMDAS?

Back

The first step is to solve any operations inside Parentheses.

Front

Solve: 3 + 5 × 2

Back

13 (First, multiply 5 × 2 = 10, then add 3.)

Front

What is the value of (4 + 6) × 2?

Back

20 (First, solve inside the parentheses: 4 + 6 = 10, then multiply by 2.)

Front

Solve: 8 - 3 + 2

Back

7 (Perform addition and subtraction from left to right.)

Front

What is the value of 2^3?

Back

8 (2 raised to the power of 3 equals 2 × 2 × 2.)

Front

Solve: 5 × (2 + 3) - 4

Back

21 (First, solve inside the parentheses: 2 + 3 = 5, then multiply: 5 × 5 = 25, and finally subtract 4.)

Front

What is the order of operations in PEMDAS?

Back

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

Front

Solve: (10 - 2) ÷ 2 + 3

Back

7 (First, solve inside the parentheses: 10 - 2 = 8, then divide: 8 ÷ 2 = 4, and finally add 3.)

Front

What is the value of 9 - (3 + 2) × 2?

Back

1 (First, solve inside the parentheses: 3 + 2 = 5, then multiply: 5 × 2 = 10, and finally subtract: 9 - 10 = -1.)
