I've got a computer with 4xquad core processors, it calculates things the same as an old 32 bit computer, just hell of a lot faster.
um, no.
and quad core has nothing to do with 32 vs 64 bit.

a 32 bit computer means it works on 32 bit 'lanes' all its components have 32 bit or smaller 'lanes' it moves around 32 bit numbers. so if a programmer needs to multiply a 64 bit number he has to do what the common core kid did. or if the system supports 64 bit operations on the 32 bit computer it has a chip which does what the common core kid did and uses the 32 bit operations multiple times and carries the overflow to build up the 64 bit result.

And yet only 35% of 3-8th graders in NY passed their CC math tests and NY is in it's 3rd year.
It's not making more sense to them.

Programmers use math libraries. They do not code bits.
Coding to the hardware is done by very few people anymore.

What is the difference between a 32-bit and 64-bit CPU?

A big difference between 32-bit processors and 64-bit processors is the number of calculations per second they can perform, which affects the speed at which they can complete tasks. 64-bit processors can come in dual core, quad core, six core, and eight core versions for home computing. Multiple cores allow for an increased number of calculations per second that can be performed, which can increase the processing power and help make a computer run faster. Software programs that require many calculations to function smoothly can operate faster and more efficiently on the multi-core 64-bit processors, for the most part.

As a programmer, I must confess, I never once gave a rats ass how the computer computed the answer, long as it was correct. This whole notion that common core teaches people how to think so they can understand computer processing and "program" better is nothing but a POS reply.. I'm wondering how long its going to take before they realize their answer is almost as dumb as common core.

they think in terms of dwords, words, bytes, nibbles, bytes etc. and all kinds of other 'resolutions' with a scalable component approach to math for all the things i mentioned in my first post, graphics,protocols,file formats, compression, audio video, physics

"What's happening"?

Addition?

Been programming for 25 years, never once thought in those terms. I have about a dozen programmers that code for me as well, never have they inquired about any of that ****.

lol, that is an answer for computer illiterate. "it makes it faster" reminds me of the sega commercials "more blast processing'"

What i told you is exactly the difference between them, larger bit lanes. obviously that too makes it faster but that is not 'the difference' between them. and again cores are irrelevant to bit resolution

I was a systems programmer so I did code to the hardware at times (assembler).
I wrote middleware/libraries/device drivers that most programmers use.

Those kids are not learning as a computer computes because they aren't learning about adding and carrying..a very straightforward method which is what a computer does.
