My basic facts Task

Walt: we are learning to quickly answer our basic facts.

this was what i did to finish the task i had to add from hundreds and tens from 100 - 20 to 100 - 90 and 1000 - 900 and so i had to stop and think then continue and there was this  one that was really hard
and i think it was 18 divided by 6 it was hard but then I figured it out.

What was the part you liked most about my maths and what you could do about it
