10.    Say it with a graph

Now this one is absolutely creative. But it also requires a little bit of work to depict. The idea is to take a graph paper and a pen and ask your partner to map these equations on the graph paper. It is best to use separate graph sheets for this. Once your partner solves these codes, watch their face light up with pleasure as they realize what the equation represents.


 x2 +y2 =9

 y= |-2x|,

x= -3|sin y|

Y=1/x will come up as ‘L’ on the graph. X2+Y2=9 will show up as ‘O’, Y=|-2x| shows up as ‘V’ and x=-3|sin y| as ‘E’. Put the Unsolved equations and the graph sheets in an envelope. And in front of the envelope write “All you need is some…” A beautiful way to say I love you in math equation.

11.    Until π runs out of decimal places

Pi (π) is the ratio of the circumference of a circle to its diameter. If you don’t find this little information romantic, well that is because it is not.

Another interesting thing about it is, just like unconditional love, the decimal places of Pi neither repeat nor does it end.

So, if you are wondering “how to write I love you in numbers?”, then Pi is the most romantic number out there. Another good thing about the Pi is that most people know about its special features. So even if your partner is not a math enthusiast, they will still know about it. Just saying something along the lines of “I will love you till Pi runs out of decimal places” is sure to make your partner blush.

12.    The love formula

If you wish to profess your feeling to your crush and your crush loves all this mathematical, then this is the perfect equation for you. Ask your special someone to map this equation on graph paper.

X2+(y – 3 2 )2 =1

  When you graph this equation, the resulting image that pops out is a heart. I assure you, your crush will absolutely love this mathematical way to say I love you and the creativity of the confession.
