How to do an easy way to do a hard addition like this
187+262=
So i do the ones like 2 and the 7 and add them
2+7=9
and the you do the tens
80+60=140
and then the hundreds and i also take the one hundred and put them with the hundreds
100+200+100=400
the add them all
9+40+400=449
so 187+262=449
or you can use the hundreds tens ones board
and in the hundred and you know the same way i did
