Question

How do you multiply and divide integers? I asked the question before but lost the paper. Help?

Answer 1

Multiplication is done like: \[0\cdot n = 0,\quad (m+1)\cdot n = m\cdot n + n\]\[(-m)\cdot n = m\cdot (-n) = -(m\cdot n)\] and for division you have to find m: \[m = \frac k n ⇔ m\cdot n = k\]
