Did Somalis understand height, width, weight, area, shape, volume? For example. They do know 'dheerer' in terms of height, they know the concept of 'balac' and width and also the concept of weight. They probably knew 'shapes' as 'qaab' but they don't seem to have identified the different 'shapes' in the world because there is no word for 'triangular, square, rectangle' which are basic shapes. Forget the more complex shapes that have developed from that.
Shape knowledge requires understanding 'points' and 'lines' and creating differing shapes. Without the basic knowledge of points and lines, it's impossible to master such field of geometry. Somalis knew an understanding of shapes, heights, width, weight, area, volume, etc. They had 'words' for these but they had no way to 'measure' it or any undestanding of how to apply their 'basic maths' of 'hal, labo, sadex,' to it because once you have the numbering system, you have a language to measure in and a good key example I can give you all is. You will never see a Somali tell you I am this tall '6 foot 2' lol they will just say 'he is tall or short', no specific measurements similar to what an aborigine would say like 1 or many, no speicific measurement in between like 1, 2, 3, 4, 5. Somalis do exactly the same thing as the aborigines with every other field of mathamatics, they do not apply any measurement. It's either his tall or short no measurement or difference in between. Their either 'fat or skinny' no measurement in between.
Hang on they have measurement where they go from 'tall, medium, short' that is a 3 point measure only or 'fat, medium, skinny'. For example 'wa dheer yahay, waa dhexdhexad yahay, ama waa gaaban yahay' or 'waa buran yahay, waa dhexdhexad yahay, ama waa caato'. What was needed to define the different levels of fat, skinny, medium by placing numbers. They couldn't do this because they probably lacked measurement tools. So it wasn't mathamatical society here but they were numerically literate and had something to start off with.
They needed to expand it further and create instruments to perform these measures. For example for weight they needed to something primitive like 'grab a big rock' as a scale balancer and measure numbers against it by the amount of force someone weight is based on the large rock. They had options to learn and expand upon mathamatics.
With fruits n Vegetables they could've developed an instrument such as rope tied to a tree, measured the rope with hal, labo, sadex, and observe the amount of force from the fruits n vegetables upon your scaling numbered somali rope, this wud show them how each weight wud be different. They could've used a rope for many times of measurements like height, width, and so many things to do proper mathamatics. They could've of used 'sticks' as a ruler to measure hal, labo, sadex, afar and begin measuring height and so many other things in their lives.
