Arrow-Puffin-3_Semester-1 Maths 123SUBTRACTION OF A 2, 3 AND 4-DIGIT NUMBER FROM A 4-DIGIT NUMBER (WITHOUT BORROWING)Example 1: Find the difference of 4278 and 52.%u2022 Subtract the ones column : 8 ones 2 ones = 6 ones. Write 6 in one's place.%u2022 Subtract the tens column : 7 tens 5 tens = 2 tens. Write 2 in ten's place.%u2022 Since, there is nothing to subtract, write 2 as it is in hundreds place and write 4 as it is in thousands place. Hence, 4278 52 = 4226Example 2: Find the difference of 7482 and 321.%u2022 Subtract the ones column : 2 ones 1 one = 1 one%u2022 Subtract the tens column : 8 tens 2 tens = 6 tens%u2022 Subtract the hundreds column : 4 hundreds 3 hundreds = 1 hundred%u2022 Write 7 thousands as it is in thousands place. Hence, 7482 321 = 71611. 6384 10 = 5. 4848 100 = 2. 2175 10 = 6. 9327 1000 = 3. 428 100 = 7. 7428 1000 = 4. 1756 100 = 8. 5100 1000 = Th H T O4 2 7 8%u2013 5 24 2 2 6 DifferenceSubtrahendMinuend Subtract the following.
