I have a question about some simple adding and subtracting numbers with Pi?

If let's say you have








10pi-3 pi, could you subtract those to make 7pi?I have a question about some simple adding and subtracting numbers with Pi?
Pi is about 3.14.





10pi - 3 pi is the same as 10 times 3.14 - 3 times 3.14





So yes, that makes 7pi or 7 times 3.14I have a question about some simple adding and subtracting numbers with Pi?
it is like terms 10';pi'; - 3';pi'; (speech marks are the like terms) is the same as if you were doing 10';x'; - 3';x'; or 10';cp'; - 3';cp';
Yes. Same as adding and subtracting variables like x.
Yes.





Thats the way to do it
Yes because they are like terms!


Its lyke doing 10x-3x=7x
