## anonymous 5 years ago How do you multiply and divide integers? I asked the question before but lost the paper. Help?

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: $m = \frac k n ⇔ m\cdot n = k$
