Another day, another discussion of base ten!<\/p>\n
<\/p>\n
Today we talked about powers of ten, and how as we have a base 10 system, each place value in our system is described by a power of ten. \u00a0This means that multiplying or dividing by 10 in our system is fairly simple and straightforward. \u00a0We took some notes on this:<\/p>\n
