my maths

My maths! My maths has been quite interesting because my maths group
is called the Ruby Lipped Bat Fish or you can call it the Red Lipped Bat Fish so we well my whole
maths group has been busy with this thing called renaming when we are subtracting.

This is really pretty fun because you can do it with + or - so you have some
numbers on top of numbers and so this is what it looks like 1564
                                                                                             - 4975

so if you can't do something you have to borrow something from next door so yeah.

My next step is to learn what to do when there is a '0' in the top number and I need to borrow from it.

Here is my 20 digit subtraction:
