Multiplying 3 Digit By 1 Digit By Regrouping
Multiplying 3 Digit Number By 1 Digit Number By Regrouping
Multiplication of numbers can be done with the help of tables
For example let us multiply 224 X 4 = ?
The multiplication can be done as follows
Step 1:
Multiply the digit at ones place
4 ones X 4 = 16 ones
As 16 is greater than 9 or we can say that 16 is a two digit number
We will write 6 ones in the ones column and carry 1 tens to the tens column.
Step 2:
Multiply the digit at tens place
2 tens X 4 = 8 tens
Now we add the carried over tens from the step 1
8 tens + 1 tens (carried over) = 9 tens
We will write 9 in the tens column
Step 3:
Multiply the digit at hundreds place
2 hundreds X 4 = 8 hundreds
Write 8 in the hundreds column.
