Hi guys! This is just another learning reflection from me.
This week, I reminded myself about expanding and simplifying numbers. Really easy really, but I forgot! So how you do it is this:
You put in the brackets the first number, and multiply it by the place value, then the brackets stop, and you put an addition sign, then the next in brackets, and so on, eg:
13578=
(1×1000) + (3×1000) + (5×100) + (7×10) + (8×1);
Expanding with powers is the same, but with powers, eg:
20870=
(2×100^4) + (8×10^2) + (7×10^1)
Anyway, goodbye, see you soon!
