a negative divided by a negative is a positive so we can get rid of minus signs
also
what number goes into 21 and 56
OpenStudy (anonymous):
2?
OpenStudy (zpupster):
21 is odd so 2 can not be divided into 21
OpenStudy (anonymous):
3 or 1? 21 / 3 = 7
OpenStudy (zpupster):
3 does not go into 56
how about 7??
