we have a problem that my parents cant help with.
846*2=(...+40+...)*2=(800 over ...+...over2+6 over...)=(400+...+3)...=...
...means blank space for a number. Can you help with this problem, so that I can figure out the rest of the problems.Thanks

from what I can tell you are using * for division (over).
Usually / is used for division and * is used for multiplication.
So I will interpret as follows ...
846/2=(...+40+...)/2=(800 over ...+...over2+6 over...)=(400+...+3)...=...
846/2=(800+40+6)/2
=(800 over 2+40 over 2+6 over 2)
=(400+20+3)
=423 
846*2=(800+40+6)*2
=(800*2 +40*2 +6*2
= 1600 + 80 + 12 = 1692
I don't know why the word "over" appears.
It shouldn't.
