Exploration 3.13 Cross Product. Read this with your partner three times. Now, do it together. 5 6 x = 4 tens 8 ones 8 50 = 40 tens = 4 hundreds 40 6 = 24 tens = 2 hundreds 4 tens = 20 hundreds = 2 thousands

Exploration 3.13 Think of as (50 + 6)(40 + 8), and reread the directions. Can you follow it better? In algebra, we learned to multiply binomials: (x + a)(y + b) = xy + xb + ay + ab. (FOIL). Do you see it now???
