What is Common Core 32 -12 and how can I solve it?

[jacobtwmurphy]

I am trying very desperately to figure out this specific problem I don't need examples of other problems i need this very very specific problem before i loose my freaking mind. Please someone explain this and show me how it works I am extremely desperate. I am told this is some sort of key, I do not know this is not my math problems or work sheet, just information I was unfortunate enough to stumble on a meme. Absolutely no one can give me a straight answer, I have even asked a math teacher and he had no idea what this was.

The first one is 32-12=20.
The second is 248*38=9386.
The methods used are subtraction by addition and lattice multiplication.
The lattice multiplication is sensible, while correct I do not see the reasoning behind the subtraction, that is not how I would do it.

the subtraction 'method' looks like hard work to me! Starting with 12, if you add, in succession, the numbers 3,5,10 and 2, you reach a total of 32. Hence the answer to 32-12 is equal to the sum of those numbers - 20. The choice of numbers to add seems somewhat arbitrary, save for the fact that the intermediate totals are round numbers - well, sort of. I'll stick with the traditional method!

Thank you guys, I am digging around looking for every spec of information on this, I can't believe this is being taught in schools now.

I understand the frustration of not being able to solve a problem and feeling desperate for a solution. However, it is important to approach problems with a calm and logical mindset in order to find a solution. In this case, the problem "Common Core 32 -12" is likely referring to a math concept called the Common Core State Standards, which is a set of educational standards for Mathematics and English Language Arts. The numbers 32 and 12 may represent specific standards within this framework.

To solve this problem, it would be helpful to first understand what the Common Core State Standards are and how they are organized. Then, you can look for resources or seek guidance from a teacher or tutor who is familiar with this concept. It is also important to note that the solution to this problem may not be a simple numerical answer, but rather an understanding of the concept itself.

In science, we often encounter complex problems that require patience, critical thinking, and collaboration to solve. I encourage you to approach this problem with a similar mindset and seek help from reliable sources. With determination and perseverance, I am confident that you will be able to find the answer you are looking for.
