DAV Class 4 Maths Chapter 2 Worksheet 5 Notes
Subtraction (5-Digit Number And 6-Digit Number)
E.g. 1.
Subtract 42565 from 80596
Answer:
Explanation:
(a) Subtracting ones:
6 ones – 5 ones = 1 ones.
(b) Subtracting tens:
9 tens – 6 tens = 3 tens.
(c) Subtracting hundreds:
5 hundreds – 5 hundreds = 0 hundreds.
(d) Subtracting thousands:
We cannot subtract 0. So, we borrow 1 ten thousands from ten thousands column. Now subtract
10 thousands – 2 thousands = 8 thousands
(e) Subtracting ten thousands:
7 ten thousands – 4 ten thousands
= 3 ten thousands
E.g. 2.
Subtract 3,30,256 from 7,98,450.
Answer:
Both the given numbers are 6-digit numbers.
Comparing their digit at lakhs place 3 < 7
∴ 3,30,256 < 7,98,450
So, the minuend is 7,98,450
The subtrahend is 3,30,256.
Arrange the digits in columnwise and then subtract.
To check the difference:
If the sum is equal to minuend then a answer is checked.
