How many arithmetic operations are there?
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.
