Mathematical markup language

Mathematical markup language (MathML) is a special computer language that helps write math equations and formulas on websites and mathematical documents, like textbooks. It is a way to make sure that math looks correct and can be read and understood by computers and humans, like you and me!

Think of MathML like a secret code that computers can understand. This special code can be added to a math problem or equation, which helps the computer correctly interpret and solve it. MathML uses specific symbols and commands that represent how numbers, variables, and other symbols are combined together to make a math equation.

For example, the equation "2 + 3 = 5" can be written in MathML like this:
<math>
<mi>2</mi>
<mo>+</mo>
<mi>3</mi>
<mo>=</mo>
<mi>5</mi>
</math>

Don't worry if it looks confusing, though! MathML is written in a way that makes sense to computers and mathematicians. By using MathML, website developers and publishers can make sure that math equations are displayed correctly and are accessible to everyone, no matter what digital device or software they use.

So, the next time you see a math problem on a website, remember that MathML was likely used to make sure it appears correctly and is easy to read and understand.
