Question 984657
 to find a number is halfway between {{{-5}}} and {{{7}}}, first find the distance between {{{-5}}} and {{{7}}} is {{{12}}}

divide the distance by {{{2}}}:{{{12/2=6}}}

add {{{6}}} to {{{-5}}}: {{{6+(-5)=1}}}
subtract {{{6}}} from {{{7}}}:{{{7-6=1}}}

so, a number halfway between {{{-5}}} and {{{7}}} is {{{1}}}
