You have been invited to join a secret cryptography society, but you have to decode this message and meet at the location.

This is the email you receive:


Let's learn your times tables!

$5$ X 8 = 74
2 X $3$ =$ $12
2$5$ X 1$0$7 = 2794
41$ $X $46$ =$ $279
3$52$ X$ $75 = $55$6
65$ $X $5$ = 9$3$1
$52$8546$ $ X $17$ = 382799$6$
94$ $X $32$6 = $78$
57$ $X $4$0$4$ =$ $1234567890
$32$0 X$ $753 = $49$467
494$ $X $46$ =$ $573
$56$ X$ $367 = $56$
683$ $X $52$85 =$ $748
$53$4 X$ $749 = $176$
7552$ $X 73$32$ =$ $278

Now you've learnt your times tables, it's time to$87$

Pbzr naq svaq hf!


Where are you supposed to meet?

Hint:

You need to go into edit mode to see it

Other hint:

Why isn’t everything encrypted with mathjax?

    $\begingroup$ Not every digit in your expressions is encoded as MathJax; perhaps this has to do with the answer. $\endgroup$ – gparyani Sep 2 '18 at 17:38
  • $\begingroup$ hmmm... maybe :) $\endgroup$ – Rohit Jose Sep 2 '18 at 17:42
  • $\begingroup$ Why are those two lines in bold? can someone edit it to make it normal text? $\endgroup$ – Rohit Jose Sep 2 '18 at 17:46
  • $\begingroup$ They are in heading font; heading font shows in bold. $\endgroup$ – gparyani Sep 2 '18 at 18:19
  • $\begingroup$ Placing a row of dashes directly below a single-line text marks it as heading, which will be rendered as bold type. If you want to draw a horizontal line, type a line of dashes with blank lines before and after it. $\endgroup$ – M Oehm Sep 2 '18 at 18:20

You are supposed to meet at...

The Training Room at 52.4754° N, 1.8845° W

The message was...

Hidden by encoding certain characters with mathjax. These numbers converted from ascii to text yielded the address above. I assumed that the final 84 was actually an 87.

    $\begingroup$ I thought I put in the co ordinates for the custard factory... but you're close enough. Well done! $\endgroup$ – Rohit Jose Sep 3 '18 at 20:54
