What I learnt to today is decimals. Our whole class was taking a lesson with Mrs tofa. She told us where does the decimal point is, told us how much power does the the decimal point does and also she told us were a the placings of them like I said. she also told us the place values of where the decimal point goes.
Here's a image where the decimals are placed in it's order. So you have ones, tenths, hundredths and so on than on the right side you have tenths hundredths thousandths and so on. This is how much power the decimal point has. So your looking at $456788 but if you put the decimal point between 4.56788 that will basically be $4 and 60c so now I know were the decimal is placed and also the power it has.
