DMAS
DMAS stands for Division, Multiplication, Addition, and Subtraction.
It is a mnemonic device used to remember the order of operations in mathematical expressions. In arithmetic, it is important to follow the correct order of operations to get the correct answer. DMAS helps us remember that the order of operations is Division, Multiplication, Addition, and Subtraction.
To understand DMAS, let's break down each operation and provide examples:
Division: This is the operation where one number is divided by another.
For example, 10 ÷ 2 = 5. In this example, 10 is divided by 2, resulting in 5.
Multiplication: This operation involves multiplying two numbers together.
For example, 4 x 3 = 12. Here, 4 is multiplied by 3, resulting in 12.
Addition: This operation involves adding two numbers together.
For example, 2 + 3 = 5. In this example, 2 is added to 3, resulting in 5.
Subtraction: This operation involves subtracting one number from another.
For example, 7 - 4 = 3. Here, 4 is subtracted from 7, resulting in 3.
Using DMAS, we know that we need to perform operations in the following order: Division, Multiplication, Addition, and Subtraction. For example, if we have the expression 10 + 2 x 5, we first need to perform the multiplication (2 x 5 = 10), and then add the result to 10, resulting in 20. If we were to perform the addition first, we would get the incorrect answer of 30.
Here are some practice questions to help you better understand DMAS:
What is the result of 6 ÷ 2 x 3?
Answer: First, we perform the division (6 ÷ 2 = 3), and then we perform the multiplication (3 x 3 = 9). Therefore, the answer is 9.
What is the result of 10 - 3 x 2 + 5?
Answer: First, we perform the multiplication (3 x 2 = 6), and then the subtraction (10 - 6 = 4). Finally, we perform the addition (4 + 5 = 9). Therefore, the answer is 9.
What is the result of 12 ÷ 4 + 2 x 5?
Answer: First, we perform the division (12 ÷ 4 = 3), then the addition (3 + 2 = 5), and then the multiplication (5 x 5 = 25). Therefore, the answer is 25.
In conclusion, DMAS is an important concept to remember when performing mathematical operations. Remember to follow the order of operations to get the correct answer, and practice using DMAS with different expressions to improve your arithmetic skills.
Remember that DMAS is just one way to remember the order of operations. Other common mnemonics include BODMAS (Brackets, Orders, Division, Multiplication, Addition, and Subtraction). No matter which mnemonic you use, it is important to follow the order of operations to get the correct answer when solving mathematical expressions.
