Three Ways You Never Knew You Are Applying The Math You learnt From Primary School

share on:

Chances are you have thought of the usefulness of the algebra, factorization and other math problems you learnt in primary school, but you are probably using them much more than you think.

While studying for a difficult math test, or enrolling in a required math class, you’ve probably thought to yourself, “When will I ever need this in real life?” while you might not be using complicated calculus on a daily basis, you can’t deny the fact that a lot of mathematical concepts drive our daily lives.

From the food we eat to the houses we live in, a lot of things in life will be confusing without math.

If you have any type of architectural project at hand, math might be just as important a tool as making use of hammer and nails. If you want to do any of these home improvement projects yourself, you will have to know how to measure and calculate everything from distance to surface area.

Want to cover your wall with wallpaper or paint? You need to be able to know how to calculate surface area, so that you know how much to buy. Thinking of changing your bathroom door? You need to make use of mathematics to avoid ending up with a bathroom door that bangs into your toilet when you try to close it.

Telling time
You most likely do this everyday but have you ever stopped to consider that maths is behind it? For instance, you start work at 9 in the morning, it takes you 25 minutes to get there, and it takes you 40 minutes to get ready in the morning. What time do you need to go to bed the night before to get your full eight hours of sleep?


Telling time relies quite a bit on addition and subtraction, but there is actually more to it than that. You use fractions whenever you think of an hour as a “whole” and minutes as its “parts,” which certainly comes into play a lot when you start at a wall clock or your wristwatch.

Multiplying and dividing fractions
It could be that you are having visitors over and you intend to make your favourite pasta dish for your visitors. You however found out that your recipe only makes four servings, and you’ve got a lot more than four people coming over.

This will require you to double the recipe—and for that, you need to know how to double a quarter of a teaspoon, a third of a cup, and two-and-a-half tablespoons.

The same is applicable if you are making less of a dish than the recipe calls for. If you only have enough garlic to make half of your favourite pasta dish, get ready to divide those fractions. This of course shows how much you have put in those maths you learnt in primary school.
