L.I Add and subtract numbers using the column method
L.I.To check our answers by using other methods.
Today I did an activity on Transum that made me use the column method. The column method is a method that you borrow from other numbers.You can borrow from higher numbers like if you don't have enough 100's you can borrow from the thousands.I found at the begging it was confusing but I started getting the hang of it.
