Question

the table below shows the elevation at which different artifacts were found in an archeological dig. which of these artifacts was discovered at the lowest elevation?

artifact	elevation
clay bowl	-725 feet
necklace	-1181 feet
bone	0 feet
arrow head	791 feet

Explanation:

Step1: Compare the elevation values

We have elevation values: 398, - 725, - 1181, 0, 791.

Step2: Identify the lowest value

Among positive and negative numbers, negative numbers are less than positive numbers and 0. Among - 725 and - 1181, since $\vert - 1181\vert=1181$ and $\vert - 725\vert = 725$ and for two negative numbers, the one with the larger absolute - value is smaller. So - 1181 is the smallest value. The artifact with an elevation of - 1181 feet is the necklace.

Answer:

necklace
