[br]In a previous lesson, you learned how to [color=#0000ff]ADD[/color] integers.[br][br][color=#0000ff][i]Summing It Up:[/i][/color] https://www.geogebra.org/m/ryw5cfbm[br][br]In this lesson, you're going to learn how to [color=#0000ff]SUBTRACT[/color] them.[br][br]To subtract two integers, switch the sign of the [color=#0000ff]SUBTRAHEND [/color](the second number) and then add to the[color=#0000ff] MINUEND [/color](the first number).[br][br]Make sure to observe the cases—[color=#0000ff]SAME[/color] signs or [color=#0000ff]DIFFERENT[/color] signs.

Use the applet below for practice[color=#0000ff].[/color] [br][br]Instructions:[br][br]1. Position the [color=#0000ff]WHITE DOT[/color] of the [color=#0000ff]BOTTOM[/color] arrow at the [color=#0000ff]ORIGIN ( 0 )[/color].[br][br]2. [color=#ff0000]SWITCH[/color] the direction of the [color=#0000ff]TOP[/color] arrow.[br][br]3. Drag the [color=#0000ff]WHITE DOT[/color] of the [color=#0000ff]TOP[/color] arrow to coincide with the arrowhead of the [color=#0000ff]BOTTOM[/color] arrow.[br][br]4. The [color=#0000ff]NUMBER[/color] (or [color=#0000ff]COORDINATE[/color]) under the arrowhead of the [color=#0000ff]TOP[/color] arrow is the [color=#0000ff]ANSWER[/color].[br][br]Repeat as many times as necessary to master the concept.

In future lessons, you'll learn how to perform other operations on integers. Hope you ENJOYED today's lesson!
