Multiplication and Addition
Today we did multiplication and addition. I am working out 4x23.
I have a colum from light to dark it means 1 to 10 and 10 to 100,
see if you can work it out first, (tops are tens, bottoms are ones).
First I have four 20 symbols and an 80 symbol, this means 4x20=80.
Below I have four 3 symbols and a 10 and a 2 symbol, this means 4x3=12.
Now I add 80+12=92.
The answer is 92.
