Step 3: Subtract the hundreds.
1 hundred – 1 hundred = 0 hundreds.
Step 4: Subtract the thousands.
9 thousands – 5 thousands = 4 thousands
Thus, 9258 – 5189 = 4069. th H t O
Example 3: Find the difference of 3952 and 2189. 14
8 4 12
Solution: Write the smaller number below the bigger in columns 3 9 5 2
and subtract starting from ones place. Regroup whenever – 2 1 8 9
required. 1 7 6 3
Thus, the difference of 3952 and 2189 = 1763.
Example 4: Subtract 398 from 3264. th H t O
Solution: Write the numbers in correct columns and subtract using 11 15
the following steps: 2 1 5 14
Step 1: Since 4 < 8, so, regroup the tens into ones to 3 2 6 4
subtract ones. – 3 9 8
14 ones – 8 ones = 6 ones 2 8 6 6
Step 2: Again, 5 < 9 so, regroup the
hundreds into tens to subtract Get it right!
the tens. Subtract 349 from 7628.
15 tens – 9 tens = 6 tens th H t O th H t O
Step 3: Again, 1 < 3, so regroup the 7 6 2 8 7 6 2 8
thousands into hundreds to – 3 4 9 – 3 4 9
subtract the hundreds.
11 hundreds – 3 hundreds = 8 hundreds.
Step 4: Subtract the thousands.
Since, there is no thousands digit in the subtrahend, so we assume
it as '0'.
2 thousands – 0 thousands = 2 thousands
Thus, 3264 – 398 = 2866.
teacher’s Encourage the students to write the numbers correctly in place value columns while subtracting two numbers
