The rules for multiplying and dividing numbers are:

two signs that are different become a negative sign
two signs that are the same become a positive sign

Multiplying or dividing a positive and negative number, produces a negative result. Multiplying or dividing a positive and positive, or negative and negative number, produces a positive result

Examples

Same signs give a positive: \((-4) \times (-5) = 20\)
Same signs give a positive: \(20 \div 5 = 4\)
Different signs give a negative: \((-14) \div 2 = -7\)
Different signs give a negative: \(14 \div -2 = -7\)
