How many arithmetic operations are there?

Answer 1

There are 6 different types of Arithmetic operations. Perenthesis, Exponents, Mulitpication, Division, Addition, and Subtraction. An easy way to remember all of these is a saying that goes.. Please Excuse My Dear Aunt Sally also known as P.E.M.D.A.S. This is an acronim that stands for the 6 operations. It goes in this specific order because if you deal with an math problem like (5 * 4) + 7 - 10 = you would deal with the Perenthesis first, 5 * 4 = 20, then exponents but since there are none you skip it, then multipication, once again skip it, division, you know what, addition (finally) add 20 plus 7, 27. Then lastly subtract 10 and you got 17. But if you come across a prblem like (7* 2) + 2 / 8* 2 you would actually do the division BEFORE the multipication since it comes first. This can only be possible if the numbers come continuous and if there...

Well I don't know why I'm going on and on about this bottom line there are 6 operations.

btw hope this is helpful considereing it was written by an 11 year old =)
