New products and upgrades are marketed at a rapid pace. The level of complexity associated with new technology, including artificial intelligence (AI) applications like ChatGPT is so great that an application is not fully implemented and absorbed before its next generation is on the market. The third version of the iPad was out while people were still purchasing the iPad 2. The diversity and depth of technology available to us are increasing at a seemingly exponential rate. This is particularly true in mathematics. In the late nineties and early part of this century, many new programmable graphing calculators (Casio, Hewlett Packard, Sharp, Texas Instruments) were introduced. Texas Instruments introduced the TI-89 and TI-84 Plus graphing calculators as well as the TI Navigator, which allows students to contribute work to the learning environment by projecting calculator work in real time for the entire class. These tools were powerful additions in the mathematics classroom. The irony is that most secondary mathematics classrooms did not fully utilize the power of the new handheld tools available to students. Why? Laptops and tablets are readily available in many classrooms and for home use. The COVID-19 pandemic pushed the envelope to support the use of powerful teaching and learning for both teacher and student. With the recent addition of AI applications, how will the mathematics classroom use technology to advance teaching and learning?DOWNLOAD<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:40%\">\n<div class=\"wp-block-group has-border-color has-black-border-color has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\" style=\"border-width:2px\">\n<media-player  load=\"visible\" id=\"vidstack-video-block_839117f6aee00a91b2e6501fd956dcf5\" class=\"vidstack-video\" title=\"Chapter 6 - Introduction\" src=\"https:\/\/s3-eu-west-1.amazonaws.com\/s3-euw1-ap-pe-ws4-cws-documents.ri-prod\/9781032028439\/chapter-6\/Chapter6-Intro.mp4\">\n  <media-provider>\n                  <media-poster\n          class=\"vds-poster\"\n          alt=\"\">\n        <\/media-poster>\n\n  <\/media-provider>\n  <media-video-layout><\/media-video-layout>\n  <media-controls class=\"vds-controls\">\n      <media-controls-group class=\"vds-controls-group\"><\/media-controls-group>\n  <\/media-controls>\n<\/media-player><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group has-base-background-color has-background has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\" style=\"margin-top:0;padding-top:var(--wp--preset--spacing--70);padding-bottom:var(--wp--preset--spacing--70)\">\n<div class=\"wp-block-group alignwide is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-7387b849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<h2 id=\"aioseo-chapter-1-exercises\" class=\"wp-block-heading\">Exercises&nbsp;<\/h2>\n\n\n\n<div class=\"wp-block-group has-border-color has-black-border-color has-base-element-background-color has-background is-layout-flow wp-block-group-is-layout-flow\" style=\"border-width:2px;padding-top:var(--wp--preset--spacing--30);padding-right:var(--wp--preset--spacing--50);padding-bottom:var(--wp--preset--spacing--30);padding-left:var(--wp--preset--spacing--50)\">\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<h3 id=\"aioseo-exercise-6-1\" class=\"wp-block-heading\">Exercise 6.1<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Define \u201ccalculator\u201d in today\u2019s society.
