How to use the MathML Operator Element: "mo"?

"mo" is the MathML Operator Element that allows you to specify a mathematical operator.

The syntax for "mo" element is:

<mo>operator</mo>

Here are some commonly used mathematical operators with MathML code examples:

Addition: +

<mn>10</mn><mo>+</mo><mn>1</mn>
    $10+1$

Subtraction: -

<mn>10</mn><mo>-</mo><mn>1</mn>
    $10-1$

Multiplication: ×

<mn>10</mn><mo>&#x00d7;</mo><mn>2</mn>
    $10\times 2$

Division: ÷

<mn>10</mn><mo>&#x00f7;</mo><mn>2</mn>
    $10÷2$

Invisible Addition: ⁤

<math><mn>3</mn><mo>&#x2064;</mo><mfrac><mn>1</mn><mn>3</mn></mfrac></math>
    $3⁤\frac{1}{3}$

Invisible Multiplication: ⁢

<mn>π</mn><mo>&#x2062;</mo><mi>d</mi>
    $\mathrm{\pi }d$

Greater Than: >

<mn>10</mn><mo>></mo><mn>2</mn>
    $10>2$

Less Than or Equal: ≤

<mi>T</mi><mo>&#x2264;</mo><mn>0</mn>
    $T\le 0$

Brackets: (), [], {}, ...

<mo>(</mo><mi>x</mi><mo>,</mo><mi>y</mi><mo>)</mo>
    $(x,y)$

N-ary Summation: ∑

<math display="block"><munderover><mo>&#x2211;</mo>
  <mrow><mi>i</mi><mo>=</mo><mn>0</mn></mrow>
  <mi>n</mi></munderover><mi>i</mi></math>
    $$\sum _{i=0}^{n}i$$

Invisible Function Application: ⁡

<mrow><mi>f</mi><mo>&#x2061;</mo><mrow>
  <mo>(</mo><mi>x</mi><mo>)</mo></mrow></mrow>
    $f\left(x\right)$

⇒ "ms" - MathML String Element

⇐ "mn" - MathML Number Element
