hello
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
example=78-34=44
70-30=40 8-4=4 40+4=44
is this right
please help
thank you captain black
i have told my son he must ask his teacher to explain this compact method and i will update incase anyone has this problem with there childrens homework.
do not know why they have to change the way they do maths in schools now much easier when i was at school
