- Find the distance between and midpoint of two numbers
distance between two numbers
The distance between two numbers, [latex]a[/latex] and [latex]b[/latex] is the absolute value of their difference: [latex]|a-b|[/latex] or [latex]|b-a|[/latex].
Find the distance between [latex]3[/latex] and [latex]-5[/latex].
midpoint
The midpoint of two numbers [latex]a[/latex] and [latex]b[/latex] is the number exactly halfway between them: [latex]M=\frac{a+b}{2}[/latex].
Find the midpoint between [latex]-4[/latex] and [latex]6[/latex].
