37. Free Shipping
Girl Math: Spending more money for free shipping
Source: @lttlefreakharry
Do you know how various brands and outlets offer free shipping if your total bill reaches a pre-stipulated amount, say $100? This means that you would not have to pay shipping on your order if you shop for $100. But do you pay the $12 shipping if your total bill is just $50, or do you buy another item for another 50 bucks and get the shipping for free? Girl math says you do the latter.

This way, you not only get free shipping but also another item at almost the same cost. The $50 difference isn’t that much if you count both the free shipping and the extra item as the perks!
38. Justifying Purchases With Girl Math
Girl Math: Round down, not up

“So, I bought this purse for $38, which means it was $30,” announced a girl mather on TikTok. Her friend added, “Round down, not up. Girl math.” The second example of girl math given had to do with spending at just one store, not multiple stores.

Justifying Purchases With Girl Math @casandra.mazzucco/TikTok
Sure, you can spend $200 at one store. But, if you don’t spend anything at all the other stores you walk into, you actually didn’t spend anything at all, if you spread it out. Girl math has a justification for everything, doesn’t it?
39. So 2 Sports Bras, a Cardigan, and a Pair Of Pants Were Free
Girl Math: $130 is $130, regardless

On TikTok, @jenn_nniffer talked about how she was in a store debating buying a pair of expensive Doc Martens. She then saw a pair of knockoff Doc Martens for a third of the price that would work.

So 2 Sports Bras, a Cardigan and a Pair If Pants Were Free @jenn_nniffer/TikTok
So, instead of spending $130, she only spent $50 on the boots, which meant she had $80 leftover. She bought “clothes and outfits” worth $80, bringing the total cost to what she was planning to spend anyway. “So, I got more for my money. And it makes sense to me,” said Jennifer. Can’t argue with that.
40. The Ultimate Heartbreak Package
Girl Math: Thinking that getting a new piercing or hair dye will fix everything
Source: @joudyelsherbiny
Dealing with heartbreak is not easy, especially if you are a girl who knows girl math and has undeterred access to the ability to make changes to her appearance. These two elements do not go well together and almost always end up with women chopping all of their hair off in a drastic, spur-of-the-moment haircut or getting the most painful piercing ever known to mankind.

The Ultimate Heartbreak Package @joudyelsherbiny/TikTok
It is their way of coping with loss and grief, and there is no reason why deriving satisfaction from changing an aspect of your life you can indeed change to forget about the one you cannot change is not healthy.
41. Red Color Blindnes
Girl Math: Overlooking red flags
Source: @gufydox
Most girls are color blind when it comes to the red flags men exhibit, but they can point out the differences between slightly different shades of the same color, say mauve and pink, in the blink of an eye. And that is all on girl math!

Red Color Blindness @gufydox/TikTok
Ask a girl which red nail paint looks better when the two shades could not look more alike, and she will instantly make her choice, but ask her to look closely at the guy she is falling for to realize his red flags, and she will be all lost. Girl math rarely girl maths when it comes to the guys they like!
42. Buying It Whole or Buying It in Parts?
Girl Math: Making an expensive thing yourself
Source: @QueenVofCoffee
Girl math is pretty simple when it comes to the dilemma of buying things whole and buying them in parts: if a particular item is just too expensive to buy as a whole, you buy its ingredients and tools instead and make it at home, even if it means spending considerably more money on the parts as compared to the whole.

Buying It Whole Or Buying It In Parts? @QueenVofCoffee/TikTok
For instance, if you think a red velvet cake is just too expensive at $40, girl math dictates you spend $60 on the ingredients necessary for it and then just bake it at home. That means you saved money!
43. The Disney Dream
Girl Math: Believing in a knight in shining armor
Source: @_shwabade_
Disney movies with the damsel in distress who gets saved by a knight in shining armor to eventually metamorphose into a beautiful princess are all delusional, and girl math digs delusion.

The Disney Dream @_shwabade_/TikTok
Sometimes, it lets you take a time out from the harsh realities of life and think that there is truly a knight in shining armor strutting around on its horse trying to find you, and he is the one who would effectively end all your woes through his infinite bank balance and even more infinite love. None of this might be true, but who said girl math was based on the truth?
44. Girl Math in Relationships
Girl Math: Thinking that a week equates to your whole life
Source: @yagirlaley
Girl math isn’t always delusional: it sometimes prompts you to make efficient life choices that can determine the course of your friendships and relationships. One of these practical choices is thinking that you do not need to contact someone because you spent a week without them because they certainly aren’t that big a part of your life!

Girl Math In Relationships @yagirlaley/TikTok
The primary tenets of girl math dictate self-love and taking care of your mental health, whether that includes making stupid mathematical calculations or taking a break from people who do not deserve your goodness. You go, girl!
45. Going for Lunch with Two
Girl Math: Having lunch with two friends so you can focus on your food
Source: @NimritFandom2
Two gal-pals having lunch dressed up in cute outfits after taking the most aesthetic, and sometimes even humbling, pictures of each other is the ultimate girl connection endeavor, but what do you do on days you are actually hungry and are going out just to eat?

Going For Lunch With Two @NimritFandom2/TikTok
Girl math says you invite two friends instead of one, so the weight of holding the conversation does not rest on your shoulders alone. With three people eating out together, you can conveniently focus on your food without having the conversation die out. Who said girl math was dumb?
46. Using 2 Hands as 5
Girl Math: Using your two hands for five things
Source: @Watching_Cl0uds
Girl math believes that girls have a unique evolutionary trait: the ability to hold five different things in their two hands and still feel like they are holding nothing. This probably stems from the fact that pieces of women’s clothing have not had pockets since the beginning of time, prompting them to hold everything in their hands.

Using 2 Hands As 5 @Watching_Cl0uds/TikTok
So now, girls can hold their keys, mobile phone, power bank with the cord attached, a drink, and their hair clip all in one hand while applying lip gloss with the other, holding the lip gloss tube in the other hand as well.
47. Having 2 Favorite Pillows from Within 8
Girl Math: Putting 8 pillows on your bed and sleeping with only 2
Source: @daejaeunique
If there is one thing that unites girls all over the globe, it is their tendency to put as many pillows on their beds as they can sustain. There is absolutely no logic behind this pillow influx because most of them sleep with just one or two designated pieces.

Having 2 Favorite Pillows From Within 8 @daejaeunique/TikTok
But having them all set up on your bed is what girl math approves of, and you cannot say no to girl math if you are a girl! Efficiency or use are not the terms in use when it comes to pillows, so it is better to keep them out of this discourse.
48. Botox is an Investment
Girl Math: Considering Botox an investment
Source: @mixedupmoney
Alyssa Davies from TikTok is also a huge propounder of girl math logic, and one of them actually makes quite a lot of sense. It calls for considering Botox an investment because you spend money to have something injected into you. So it is quite literally an addition to your body, making it an investment!

Botox Is An Investment @mixedupmoney/TikTok
The Botox materials do not go anywhere; they stay within you and with you, and thus, it is not wrong to call the whole endeavor an investment. You give money and get Botox to augment your visual appeal, making it the perfect investment for your beauty!
49. Thinking a Bleak Future Bright
Girl Math: Daydreaming about a future with a disinterested guy
Source: @Kyaandere
We won’t say girl math is always practical: it may sometimes allow you to daydream while doing the menial tasks of life and imagine a healthy, loving life with your crush who does nothing but play League of Legends and ignore your text messages all day.

Thinking A Bleak Future Bright @Kyaandere/TikTok
But there is nothing wrong with distracting yourself by letting your imagination go astray, as long as you continue believing in girl math and do not lose a grip on reality! We must warn you that this endeavor is quite risky and should only be indulged in if you can promise to do that only sometimes.
