How to Solve Addition and Subtraction Sums with Parentheses in Grade 4
FAQs on Addition and Subtraction with Parentheses – Class 4 Maths Worksheet
1. What is the order of operations for Class 4 maths with parentheses?
The order of operations for Class 4 maths requires you to solve the part of the sum inside the parentheses (or brackets) first, before doing any other addition or subtraction. This is the first and most important step in solving multi-step problems.
- Step 1: Look for the part of the sum enclosed in brackets, like ( ).
- Step 2: Solve the calculation inside these brackets first.
- Step 3: Once the bracket is solved, perform the remaining additions and subtractions from left to right.
2. How do you add and subtract with parentheses?
To add and subtract with parentheses, you must always calculate the expression inside the parentheses ( ) first, and then use that result to complete the rest of the sum. Following this rule ensures you get the correct answer.
For example, in the sum 15 + (10 – 4) – 2:
- First, solve the part in the bracket: (10 – 4) = 6.
- Now, replace the bracket with its answer: 15 + 6 – 2.
- Finally, solve from left to right: 21 – 2 = 19.

- Number Sense: It strengthens a student's fundamental understanding of how addition and subtraction work together.
6. What is the rule for brackets in maths for Grade 4?
The main rule for brackets in Grade 4 maths is that you must always solve the calculation inside the brackets before any other part of the equation. This is a fundamental concept in the order of operations, sometimes introduced as PEMDAS or BODMAS, where 'P' or 'B' stands for Parentheses/Brackets.
7. How does this worksheet help with concept retention?
This worksheet uses varied question formats and repetition to ensure students effectively retain the concept of solving sums with parentheses. It is structured for both practice and reinforcement.
- Concept Reinforcement: It provides repeated practice on the core rule of solving brackets first.
- Mixed Question Types: The worksheet includes fill-in-the-blanks, solve-and-circle, and standard sums to keep students engaged.
- Hands-on Practice: Actively solving problems helps transfer theoretical knowledge into practical skill, improving long-term memory of the order of operations.
8. Can I use this worksheet for homework or revision?
Absolutely, this worksheet is an ideal resource for both homework assignments and revision sessions for Class 4 students. Its clear instructions, focused topic, and included answer key make it perfect for independent practice at home, allowing students to build confidence in solving mixed operation sums.
9. What kind of problems are in the add subtract parenthesis five numbers worksheet?
This worksheet contains problems where students must add and subtract a sequence of five numbers, with some numbers grouped inside parentheses to dictate the order of calculation.
- Problems like 45 + (30 – 10) + 5 – 7 = ? require solving the bracket first.
- Questions may also ask students to place brackets correctly to arrive at a given answer.
- The format includes a mix of question types to provide comprehensive parenthesis practice.
10. Why is it important to solve the numbers in the brackets first?
Solving the numbers in brackets first is a universal rule in mathematics that ensures everyone gets the same correct answer for the same problem. This rule, known as the order of operations, prevents confusion in multi-step calculations. For example, in 10 – (4 + 2), solving the bracket first gives 10 – 6 = 4. If you did not follow the rule, you might get an incorrect answer.
