DAV Class 4 Maths Chapter 2 Worksheet 1 Notes

• The numbers which we add are called addends.
  Example, 2 + 3 = 6. Here, 2 and 3 are addends.
• During addition, first we add ones, then tens, then hundreds, then thousands, then ten thousands and lastly lakhs.
• In addition if we change the order of addends, then also the sum of addends remain the same.
• When we add zero to a number, the sum is the number itself.
• Minuend is the number from which we subtract. Subtrahend is the number to be subtracted and the result or answer of subtraction is known as difference.

Example,

• When we cannot subtract a larger number from the smaller number then we borrow a number from its corresponding place value.
• To check the difference whether it is correct or not we add subtrahend and the difference which should be equal to minuend.
• When we subtract zero from a number, we get the number itself.
