Here’s the second semi-final match of The Big Internet Math-Off. Today, we’re pitting Angela Tabiri against Ayliean.
Take a look at both pitches, vote for the bit of maths that made you do the loudest “Aha!”, and if you know any more cool facts about either of the topics presented here, please write a comment below!
Angela Tabiri – Six everyday examples of mathematics applications
Mathematics is difficult. Mathematics is abstract. What will I use maths for after high school? In this contest, we demonstrate six applications of mathematics in everyday life.
Starting your morning in Ghana usually involves a breakfast of “koko” and “koose”. Koko is a porridge made from millet while koose is made from beans. The koko seller stores the porridge in an aluminium cylindrical object. Using the mathematics of computing the volume, the koko seller can compute the quantity of porridge and how much the portions need to be sold in order to make profit. The volume of the cylinder can be explained as each layer of the cylinder consisting of circular surfaces so the sum of all these circular surfaces gives the volume of \(\pi r^2 h\).
When joining a road from a side street, you estimate the speed of the driver in the lane you are joining to see if the vehicle will be a safe distance from you by the time you join the road. If the estimation shows that the speed is high and you are not safe to join the road, you need to wait for the road to clear up in order to safely join. This involves speed, calculated as the ratio of distance to time.
In buildings which are tiled, mathematics is used to compute the area of the floor to estimate the quantity of tiles needed to tile the floor. If there are special designs to be incorporated, maths is used to compute the precise location where the designs need to be in order for the artwork of the tiles to come out beautifully.
When window frames are not fixed properly, the smallest space will allow water to seep in when it rains. If the right angle is accurately fixed at the corners of the window frame, this will reduce the chances of rain seeping through the window.
Malaria is a challenge especially in developing countries. Anytime you test positive for malaria, immediate treatment is recommended. The treatment prescribed is the stage of malaria. Mathematics is used in determining the dosages to ensure that they are taken in the right quantities and at the right time.
The wall clock shows a twelve hour time when we have twenty four hours. With modular arithmetic, we can convert times from 13:00 to 24:00 to times between 0.00 t0 12:00. We do this by computing the remainder when divided by 12. For instance: 13:00 becomes 1:00pm since 13 leaves a remainder of 1 when divided by 12.
In conclusion, mathematics is the foundation for most professions due to its universality. A deep understanding of mathematical concepts and availability of interesting learning materials will make it accessible to all.

I’m voting for Ayliean
I’m voting for the Scroggs Math Off Sticker Book – it’s so cool, y’all need to get in on the fun. The sticker economy is a wild ride!
Lovely video from Ayliean! Still got the counting song stuck in my head…
I spent all of yesterday with a Chappell Roan song as earworm, so numbers and stars will make a nice change, thanks Ayliean
I’m voting for Angela
Six applications of Mathematics in daily life is great
Voting for Angela. Nothing better than someone mathematically and accurately representing your morning Koko and the thoughts you get crossing a road in Ghana
Angela all the way ,bringing excitement to Ghanaians
Am voting for Angela Tabiri. Just after watching her video she has drawn my attention to the simple daily mathematics we do that we are not even aware
I am voting for Angela
#MathsIsEverywhere this was insightful! Thanks Angela
It’s fantastic of how Angela demonstrates the application of Mathematics in daily life. I surely vote for Angela.
Thank you Ayliean for the 1-5 counting game. The combinatorics in here is very interesting. I just love Mathematics.
Dr. Angela Tabiri has my support. She’s a mathematician par excellence….
Application of mathematics is interesting! She explains things that I couldn’t think how math would be involved! Kudos Angela
Voting for Angela
I am Voting for Angela
My vote is for Angela. She is a mathematician indeed.
I totally love Angela’s expose on Math in every life.
Angela, you are the best
I’m voting for Angela, she is phenomenal with numbers.
My vote is for Angela, she’s indeed a pro in mathematics. Go Angie…
I’m voting for Angela. She’s a genius. The Loki analogy was perfect application of math.
Miss Angela all the way
What a great pitch from Ayliean! Appreciate how you connected music, star polygons, modular arithmetic, and joyful math(s) all together.
Wishing Angela well.
Voting for Angela
I voted for Ayliean.
This is another great example of them using math(s) to create art. This time is musical instead of visual.
Votting for Angela
Math is very essential in every profession and we cannot do without it daily
She has very good voice to attract the attention of students
She give a good real-life
Angela Tabili is good
Very explanatory. Well done Angela.
Voting for Angela Tabiri
Angela you are simply the best mathematician in the world
Angela makes maths look simple and lovely.
She’s my maths superhero.
Best wishes ❤️
Go Angela
Angela is a genius period
Voting for Angella. Usually layman people are not aware of how maths is part of their daily lives. It was nice to listen to her exampless. And hopefully people will stop being afraid of maths :).
Voting for Angela Tabiri
Amazing ✅✅ thanks for helping us
As we all vote for our preferred mathematician let us try tell our kids and family members that maths is not scary one bit. Direct them to such sites as this to know maths is fun and it is the only subject one can easily score hundred percent. Thanks everyone
Awesome
Dr Angela is the best
Angela go for Gold
Dr Angela is simply the best
Angela for the win.
Dr. Angel is really the best
