  • Evaluate the addition problem.
  • Solve the subtraction problem.

Each concept is explained to class 4 maths students using illustrations, examples, and mind maps. Students can assess their learning by solving the two printable worksheets given at the page’s end.

Download the addition and subtraction worksheet for class 4 and check the solutions to the addition and subtraction questions for class 4 provided in PDF format.

What Is Addition?

Addition: The process of combining two or more numbers together is called addition.

Sum: The result obtained by addition is called sum.

Addends: The numbers that are added to get the sum are called the addends.

Properties of Addition:

Step 1: Arrange the numbers in columns according to the place value.

Step 2: Start adding the numbers from the ones place and continue to the left.

Step 3: If the sum is less than 9 then write it below the corresponding place value and if it is more than 9 then write the ones digit below the corresponding place value and carry the tens digit to the next column in the left.

Step 4: Continue the same process.

Example:

Question: Add 2354 and 1732.

Answer: Arrange the addends in columns according to their place value.

What Is Subtraction?

Subtraction

Subtraction: The process of finding the difference between the two numbers is called subtraction. The bigger number is subtracted from the smaller number.

Minuend: The bigger number from which the smaller number is subtracted is called minuend.

Subtrahend: The smaller number which is subtracted from the bigger number is called subtrahend.

Difference: The result of subtraction is called difference.

Properties of Subtraction:

Step 1: Arrange the numbers in columns according to the place value.

Step 2: Start subtracting the number from the ones place and continue to the left.

Step 3: If the minuend is smaller than the subtrahend, then borrow 1 from the digits in the left column.

Step 4: Continue the same process.

Example:

Question: Subtract 1732 from 2354.

Answer: Arrange the numbers in columns according to their place value. Write the minuend first and then the subtrahend below it.

Properties of subtraction

Did you know?

  • If 0 is added to any number then the number remain itself.

    Example: 2456 + 0 = 2456

  • If 0 is subtracted from any number then the number remain itself.

    Example: 560 – 0 = 560

  • If any number is subtracted from 0 then the result is the negative of the number.

    Example: 0 – 40 = -40

Common mistakes:

The place value of the digits is not considered in the calculations.
