Zero and one in multiplication
We focus on how zero works in multiplication. For example, 4 x 0 means four groups of zero... which totals nothing, a big fat zero! The same happens with 0 x 9, or zero groups of 9. We review how 1 works, also. Mathy my mascot would rather study number 9 though, so he has to insert a problem... can you solve 9 x 9? :)
