Multiplication 2 times: $(-2)\times (-2)=4$

Multiplication 4 times: $(-3)\times (-3)\times (-3)\times (-3)=9\times 9=81$

Multiplication 6 times: $(-1)\times (-1)\times (-1)\times (-1)\times (-1)\times (-1)=1\times 1\times 1=1$

Hence, when a negative integer is multiplied even number of times, the result is a positive integer.
