Understanding Place Value

To subtract 3-digit numbers effectively, it’s crucial to understand place value. Let’s consider the number 436. This number consists of:

  • 4 hundreds

  • 3 tens

  • 6 ones

When we write it out, it looks like this:

  • Hundreds place: 4

  • Tens place: 3

  • Ones place: 6


Step-by-Step Subtraction

Let’s subtract 312 from 436 using place value.

Step 1: Subtract the Ones

  • We have 6 ones and need to subtract 2 ones.

  • 6−2=46 - 2 = 46−2=4

  • Write 4 in the ones place.

Step 2: Subtract the Tens

  • We have 3 tens and need to subtract 1 ten.

  • 3−1=23 - 1 = 23−1=2

  • Write 2 in the tens place.

Step 3: Subtract the Hundreds

  • We have 4 hundreds and need to subtract 3 hundreds.

  • 4−3=14 - 3 = 14−3=1

  • Write 1 in the hundreds place.

Putting it all together, 436 minus 312 equals 124.
