Class 3 Maths - Order of Operations with Addition and Subtraction

Parentheses, also known as brackets, act as a signal to solve a specific part of a math problem first, even if it goes against the usual left-to-right rule. They change the natural sequence of solving an equation.

For example, in the problem 20 - (10 + 5), you must solve the part inside the parentheses (10 + 5) first to get 15. Then, you complete the sum: 20 - 15 = 5. Without parentheses, the problem 20 - 10 + 5 would be solved from left to right, giving a different answer of 15.

The rule for addition and subtraction is that they have equal priority, so you should solve them in the order they appear from left to right. This only applies after you have solved any calculations inside parentheses.

• For example, in a problem like 50 - 20 + 10, you first solve 50 - 20 to get 30.
• Then, you take that result and solve the next part: 30 + 10, which equals 40.

To solve a three-term problem with mixed addition and subtraction, you must follow the correct order of operations. This worksheet provides excellent practice for mastering this skill.

1. Check for Parentheses: First, look for any brackets or parentheses. If you find any, solve the calculation inside them first.
2. Move Left to Right: If there are no parentheses, start from the far left of the equation and solve the first two numbers.
3. Complete the Final Step: Use the result from your first calculation and apply the final operation with the third number to find the answer.

Yes, a complete and accurate answer key is included with this Class 3 maths order operations worksheet. The answer key makes it easy for parents and students to check the solutions and verify their work, which is essential for independent learning and self-assessment.

Yes, this worksheet is specifically designed for Grade 3 students, typically aged 7-9 years. The content is aligned with the learning objectives of the CBSE and NCERT curriculum for Class 3 Maths. The problems use simple numbers and a clear, large-font layout to ensure they are age-appropriate and easy to understand.

This worksheet helps Grade 3 students develop several crucial mathematical and cognitive skills beyond basic calculation.

• Problem-Solving: It teaches a systematic approach to solving multi-step problems.
• Logical Reasoning: Students learn to apply rules (like order of operations) consistently.
• Conceptual Clarity: It reinforces the importance and function of parentheses in calculations.
• Accuracy: Regular practice with these three-term addition and subtraction problems improves calculation speed and accuracy.

Teaching the order of operations to kids is best done with simple rules, clear examples, and plenty of practice. Start with problems that only involve addition and subtraction to establish the left-to-right rule. Then, introduce parentheses and explain that they are like a 'VIP section' that must be dealt with first. Using a practice worksheet like this one provides the structured practice needed for concept reinforcement.
