(positive number) x (positive number) = positive number

(positive number)/(positive number) = positive number

(positive number) x ( negative number) = negative number

(positive number)/( negative number) = negative number

(negative number) x (negative number) = positive number

(negative number)/(negative number) = positive number

atomic number = number of proton in an element

number of proton = number of electron

mass number = number of proton + number of neutron

therefore...

atomic number = mass number - number of neutrons
