There are two types of short methods in multiplication. There is one which use the left of the column, and all you have to do is carry the tens units (T), but because it is being times by the units you don’t need to plus any thing to it.
Non plus short method!!!: In order to succeed the short method you need toknow your times tables, because you may have to comeacross hard questions. Now your ready to start. Thefirst thing you have to do is times your units by theunits, make sure you don’t put it in the wrong columnor it will change your answer. You may come acrosssums that you have carry the tens, and then times theunit by the tens. After times the unit by the tens and ifyou carried the tens plus it on make sure you don’t youdon’t times it or it would change your answer. Last ofall you times the units by the hundreds and again if youcarried the tens plus it on. EG:1 979 x8 2 7 EG:2 979 x EG:3 979 x
If you times a two digit number you have to plus it, becauseyou have to times it by the tens and units. So first you haveto times the bottom unit by the top unit in the right placevalue. Then times the unit by the ten. And then you times theunits by the hundreds. Then times the tens on the bottom bythe top units. After times the tens by tens on top. Then timesit by the hundreds.
