Description
"Multiplication of Integers" PPT
Part One: Review Import:
1. Multiplication of powers with the same base: am.an=am+n (m,n are both integers)
2. Power of power: (am)n=amn (m,n are both positive integers)
3. Power of product: (ab)n=an.bn (n is a positive integer)
PPT on multiplication of integers, part 2: independent completion of independent exploration
(1)2a a=2(a a)=2a()
