yes the pattern of multiplying binomials. 42 = (40 + 2) and 38 = (40 - 2) so
42 x 38 = (40 + 2)(40 - 2) => use the pattern of the difference of squares
= 402 - 22 = 1600 - 4 = 1596

12+ 6 is the number on the outside add up to the on in the middle
You add as many zeros to the number as you have in the power of 10.
name two smaller arrays you can use to find the product
12 x 11 = 132. The numbers on the outside add up to the one in the middle.
you can do 5 12 times

You can use the product from 4x7 to find the product of 8x7 by doubling the answer to 4x7. The product of 4x7 is 28 and the product of 8x7 is 56 (28 doubled is also 56).
You add as many zeros to the number as you have in the power of 10.

you have to follow the pattern that they give you if you want to make your product. but you do not have to use the same colors
give a poo
You cannot since there is no product of a single number!
how would you use a hundredths grid to find the product 0.3x0.8 ?
No, not directly from the code. You can determine manufacturer OR use the info on the product itself to do that. By contacting them, you can find out what stores they supply in your area.
