Because i never visit a single destination, the 9 total immediately made no sense to me. "What about visiting Sedona and Cabo?" Cabo, interrupted by chubasco, and flight to Vancouver?, etc. And all three? Ferry and sweaty bicycling through Sonora to Sedona from Cabo . . . . you see the immediately exponential problem. A minimum 81, with such permutations as who actually prefers b&b over camping?No one in their right mind or avoiding communicable disease, which factor introduces a possible stop in Tijuana. The unpredictable independent factors threw me completely. (This was the root of my difficulties in word problems i mentioned under the Venn diagramming Study Hall. Only making the actual trip[s] can collapse the likely, probable, permutations, and thus computation can only occur in hindsight) I remember a discussion with an anthropologist, who pointed out that the most common numbering done by one tribe was, use of 1, 2, , 3, and the heuristic " many" for ANY number beyond that, in conversation, which at first confused him. We can hold about 7 to an individual maximum of 9, individual objects in mind at once. Research shows that this number occurs as a maximum in a corvid and a cursorial mammal i know of. So, counting is handy, and we all retain some wonderfully implicit understanding of the Babylonian base 60 system, with its factors of 2, 3, and 5. The seemingly weord factor of 7 in our weeks is explained by the near-perfect quartering of the moon, highly important before the offensive advent of artificial night lighting. Living with a Wolf, i noted my difficulty in negotiating wild, natural country when moonlight was less than 1/2 illuminating. Thus the medieval " fortnight", 14 nights, made sense! I still take offense that calendars are manipulated, as 13 actual months occur in 364 days. Our circadian cycling of 45 minutes later each day being the most comfortable "postcession" ( or whatever word connotes the opposite of precession. It's a known brain thing, btw), fits PERFECTLY with moon ilumination change. We have departed from our natural neurological cycling. I first noted when first reasonably allowed freedom to live and play with peers on dark, unlit island groups in subtropical region, where we fell into thses rhythms before puberty, though adults remained captive to ridiculous, if attractive, Babylonian numeric clocks. Surfing life, like the solar-dependent lives of farmers, is natural and pleasurable due to this entrainment with life and earth/moonlight, in profound contrast to the irascible violence of nutty "civilization." ( i am not so much meandering here, as happy to be exhausted right now, while reviewing and learning more math.)
The example given is simplified for ease of understanding. The usual mathematical word problems are not designed to accurately describe the world, its supposed to make mathematical ideas less abstract to someone learning them. A typical math problem can be represented like " A man buys 700 apples and 400 oranges, how many apples and oranges does the man have after buying them? " If you think about it too deeply ( why is he buying so much fruits? can he afford it? what if he eats some? ) then you are missing the point. The question is simply designed to introduce a beginner into the concept of algebra. In this case using apples and oranges instead of the usual placeholder x or y. Is it unrealistic? Of course. Does it make sense? Yeah..
You know it's gonna be a good day when you get a little History with your Math.
The real question is, do you start counting on your thumb or index finger?
Thumb for me!
From the pinky to the thumb for me 😂😂
@@fenixrock I just tried that and I felt like I forgot how to count hahahaha
Does anyone else count to 10 on one hand? 🤭
Thumb!
ty for posting!
