not to mention $\frac{e^{-t}}{y^3+1}$

To type Mathematical Symbols on your PC:

**1) USE WINDOWS EMOJIS: **

To type ⅷ∀√∛∞∑²³ⁿ∃∞∫≈≡≥ and many more. Simply press windows key together with . to bring up the emoji keyboard, then select Ω or ∞to bring up the maths palette. **VERDICT:** works with any app on PC including Facebook, Twitter, MS Office etc etc. For this reason I totally ❤ this hack 😍👍!

**2) INSTALL GREEK AS A SECOND LANGUAGE: **

Great if like me you regularly use letters like

π = 3.14…

θ, φ for angles

Σ for “sum of”

α, β, γ for unknowns (if a, b, c are already in use)

λ , μ and σ for statistics.

On a PC go to control panel – regions – language preferences then download the Greek language. Now you can switch effortlessly between Greek and English by pressing windows key and space bar, while hardly missing a beat. **VERDICT:** easy as π to set up and is the α and ω of Greek character input. Your PC shows labels ENG or ΕΛ in the taskbar (bottom right) to remind you which language you are inputting.

**3) GOOGLE THE SYMBOL THEN COPY AND PASTE IT INTO YOUR DOCUMENT:**

Self-explanatory. **VERDICT:** it works. It takes a while.

**4) USE LaTeX: **

The gold standard! Type expressions like:

$x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}$

effortlessly and intuitively. Here’s how to type that equation: x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}**VERDICT:** love love love it! LaTeX is what I used for this blog. Well worth the short time it takes to learn the basics, then becomes effortless and intuitive. For instance \leq gives you $\leq $, and \div gives a divide sign $\div$. Only works on LaTeX compatible apps e.g. in Word press alt together with = and on WordPress install the LaTeX add-on.

**5) USE ALT SHORTCUTS: **

For instance, hold down alt key while pressing 246 might give you ÷ sign.**VERDICT: **almost useless as the same number combination can give different outputs in different programs.
