How can you use a 2s fact and a 1sfact to find 3x8?
To find 3x8 using a 2s fact and a 1s fact, you can decompose the multiplication. For example, you know that 2x8 equals 16 (a 2s fact), and you also know that 1x8 equals 8 (a 1s fact). You can then use these to find 3x8 by adding 2x8 and 1x8 together: 16 (from 2x8) + 8 (from 1x8) equals 24, which is the answer for 3x8.
