Distributive law of multiplication have roughly three categories: first, the average distribution method. Such as: (125+50) *8=125*8+50*8. 125 and 50 to 8 and the average distribution, to multiply. Not only one of the numbers is multiplied by 8, thats not fair, is not the average ...
It is the basis not only of mental calculation, as we are about to see, but it is the basis of the traditional written method as well. Moreover, it is a theorem that we can prove.5. How can we apply the distributive property to mental calculation? Decompose or expand the multipli...
