Why learn how to solve math problems that involve integers?<\/h2>\n

Beatrice is an oceanographer, and she’s\u00a0studying the composition of undersea lava flows off the coast of Hawaii. As part of her work, she’s on a scuba diving mission to collect samples of lava rock at\u00a0various depths. She and her team dive down and then follow\u00a0the lava flow from the point of eruption along\u00a0hills and valleys that have formed over time, collecting samples along the way.<\/p>\n

Today, Beatrice and her team start their dive by going [latex]110[\/latex] feet\u00a0below sea level. After collecting a few samples, they gradually come back up to sea level. Along the way, they notice a lava formation at [latex]23[\/latex] feet below sea level, so they do another dive to collect samples from it.<\/p>\n
