Hi Raj,

Thank you, so there are three; all on Unit 2-Week 1.
1st row, 3rd last 2+44+9+24 (we managed to get to 79 only by calculating it on the abacus backwards!) but when you go to add the 9, there is no 10 bead.

2nd row, 3rd in 8-4+49+32, again, cannot +9

3rd Row, 4th in 82-40+9+6, again cannot add the 9 because there is no 10 bead.

Thanks…[Read more]

Hi,
There are three or four questions on the worksheets where we are unable to follow the +9 rule as we are unable to +10. Is anyone having trouble with this?

Thanks,
