1. The user asks how to write math digitally, which means typing math expressions using LaTeX or similar notation. 2. To write math digitally, you use LaTeX syntax, which is a markup language for math. 3. For example, to write a fraction, you use \frac{numerator}{denominator}. 4. To write a square root, you use \sqrt{expression}. 5. To write powers, you use ^{exponent}. 6. Inline math is enclosed in single dollar signs $...$, and display math is enclosed in double dollar signs $$...$$. 7. For example, the quadratic formula is written as $$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$$. 8. This way, math can be typed and displayed clearly in digital documents or chats. 9. Practice writing simple expressions like $x^2+3x+2=0$ to get comfortable. 10. Many platforms support LaTeX rendering, so your typed math will appear formatted.
