The Earth
The Earth is a planet. Humans live on that planet. Other animals live on the Earth, as well.

Algebra
Algebra is a category of math and includes lineair equations, such as:

$$\frac{3x}{2} +2x-4 = 8-2x \iff 3x + 4x - 8 = 16-4x \iff 11x = 24 \iff x = \frac{24}{11}.$$

Factoring is fun!

$$5(2n-1) + n(2n-1) = (5+n)(2n-1). \text{This is all because of the distributive property.}$$

There exists a graph for the lineair function $$y = 2x+4$$: { "version": 2, "width": 400, "height": 200, "data": [ {			"name": "table", "values": [ {					"x": 0, "y": 4 },				{					"x": 1, "y": 6 },				{					"x": 2, "y": 8 },				{					"x": 3, "y": 10 }			]		}	],	"scales": [ {			"name": "x", "type": "linear", "range": "width", "zero": false, "domain": { "data": "table", "field": "x" }		},		{			"name": "y", "type": "linear", "range": "height", "nice": true, "domain": { "data": "table", "field": "y" }		}	],	"axes": [ {			"type": "x", "scale": "x" },		{			"type": "y", "scale": "y" }	],	"marks": [ {			"type": "line", "from": { "data": "table" },			"properties": { "enter": { "x": { "scale": "x", "field": "x" },					"y": { "scale": "y", "field": "y" },					"y2": { "scale": "y", "value": 0 },					"interpolate": { "value": "monotone" },					"stroke": { "value": "steelblue" },					"strokeWidth": { "value": 3 }				}			}		}	] } When taking the absolute value of a function, there will be a vertex. For example, look at the graph of $$f_{1}(x)=x-5+|2x-6|$$.
