I recall my son coming home and doing homework math called BODMAS, BIDMAS and PEMDAS or some such crap.
I could not believe it when I was able to prove to him that using this insane system you could have one equation come to two separate answers that technically were both correct.
I showed it to my Uncle who was prior to his passing a quantity surveyor with a Masters degree in Math and he was appalled calling it dangerous and liable to cause serious accidents in construction.

I don't understand how schools adopted this new math crap. It's the most retarded way of doing math

"Common Core" is the "New Math" of the 21st century.

And what a nightmare it is
It's retarded and so are the idiots that came up with it.
I am a teacher (not in America) and I have never and will never teach a child to do multiplication the first way. i may show them using blocks how it all works ie we will make 17 groups of 23 and then look at the fact that we have 10 groups of 3 and 10 groups of 20 as well as 7 groups of 3 and 7 of 20 so that they understand what is happening (we are talking 8 year olds who don't do abstract thinking too well yet.) But then I show them the long multiplication method and as we work through how to do it we refer back to the blocks but under no circumstances would I teach the rubbish at the top as the way to complete the problem.

In our state, they fought for over 20 years to get funds for converting to new math. By the time they did, most of the rest of the world had deemed it useless and reverted to standard math. But these bozos were so determined to follow through, that they went ahead with the new math. What a nightmare.
I grew up in California and they were one of the first to do the new math, and nobody understood it, especially the teachers ( who could blame them ) . This is what happens when beaurocrats are too busy trying to justify their existence.

Now that's all about working smarter not harder.
