Overseas Competition->Knowledge Point->Calculation Modules->Whole Numbers->Whole Numbers Multiplication and Division Overseas In-curriculum->Knowledge Point->Operations of Numbers ->Multiplication of Whole Numbers->Multiplication of Multi-Digit Numbers and 1-Digit Numbers->Multiplication of 3-Digit and 1-Digit (with regrouping for more than once)
Stack the two numbers as shown below ,~ lining up the unit digits  Remember that the 7 in 272 stands for 7 tens(70) ,the first 2 in the 272 stands for 2 hundreds(200)  First, multiply the ones~ $2\times3=6$~, regroup the 0 tens to the tens column  Write ~6 in the ones place.  Then,~ Multiply and add the tens .~$3\times7+0=21$  Write 1 in the tens place and regroup the 2 hundreds.  Last, multiply and add the hundreds.~$3\times2+2=8$  Write 8 in the hundreds place
