could anyone help me with my son maths homework
it is subtraction using a compact method
it has all changed since i was at school
is there anyone who knows what this is
i was thinking it maybe this
70-30=40 8-4=4 40+4=44
is this right
I don't know the method, but if what you write is correct it still makes no mathematical sense.
