Like pizza with a huge circumference? Good, because today is Dave (from Accounting)’s birthday and his only wish is for a math-themed email.

In honor of our favorite human calculator, here are the 5 greatest math equations:

1. Salad + Fried Chicken – Salad = Perfect
2. 10:1 = optimal marshmallow to cereal ratio
3. Robe + Bunny Slippers = Us right now
4. Using this coupon > Not using it
5. 3,278,594 x 0 = Number of people still reading this.

Now enter this code at checkout on our totally math-free app (Sorry Dave) for some extra guac* on your burrito this weekend.

Coupon code:

Need another coupon? No problem. Just tweet this and we’ll hook you up with a bonus code: “Happy International Dave at @EAT24 Day!”

You’re the pi to Dave’s pie.

Love,

EAT24

*Since law is kind of like math (because we will never understand either of them), here is a poem our lawyers wrote: This $2 coupon expires on Sunday, March 22nd at 11:59PM PDT (but we know you’ll order way before that because you’re already thinking about mozzarella sticks aren’t you @SJHatzi?). You must be an EAT24 member (like @sofifi323, duh) to use the code, which can only be used once on orders of $10 or more when paying with Credit Card, PayPal, or Google Wallet (or @burgab0o Bucks). That’s it! You’re done. Now let’s go cosine some tangents, multiply a rhombus, and toast to birthday boy Dave. If you already ordered and just need some entertainment while you wait, you should @AskAJAnything.
