| Spanish ax or phrase: llevando por un factor |
| Hello. This is from a list of the species of mathematical practice to be done my major school pupils: • Multiplicaciones llevando por un factor. Going right into UK English. many thanks for your aid :) Simon |

| Explanation:From the list of activities, that looks together though this is the next step after discovering the multiplication tables (ie, multiplying a single-digit number by one more single-digit number). It seems logical that the following step would certainly be to multiply a multi-digit number through a single-digit number, which entails carrying the 10s to the next position to the left. ~ that, they would certainly go top top to multiply a multi-digit number by an additional multi-digit number, yet that looks favor it doesn"t happen in this year/grade. (BTW, go anybody know exactly how to protect against an apostrophe acquiring a backslash pre-appended to it?) |

This teaches the concept of carrying the tens, and prepares the students because that multiplying a multi-digit number by a multi-digit number, due to the fact that you take the digits of the multi-digit multiplier one by one. That"s why I suggested "multiplying *BY* a single digit", no "multiplying single-digit numbers" For what it"s worth, i actually know some math teachers that teach single digit multiplication as carrying: 9 x 9 is 81, compose down the 1 in the ones column, lug the 8, 8 add to 0 is 8, write down the 8 in the 10s column. The said, ns agree: because most civilization memorize their multiplication tables up to 10 or 12, whether or not there is (or human being view there to be) transferring in single-digit multiplication deserve to be debated.
